No Body, No Jury: The Day the State Explained Why There Is Nothing Left to Find

Steven Cozzi went to work on the morning of March 21, 2023, at a law firm on South Belcher Road in Largo, Florida, and nothing of his has ever come back. Not him. Not the watch he wore, which paired to nothing but his own phone. His phone itself was still sitting on his desk when people started looking for him. Three and a half years later the State of Florida is asking a single judge to find that Tomasz Kosowski murdered him and to consider putting Kosowski to death for it, and the State is asking that with no remains, no recovered property, and no place anyone can point to and say: there.

Day 5 was the day the State stopped working around that hole and walked straight into it.

It put on a garbage truck driver, a crime scene investigator, and the man who runs a landfill, one after another, and what those three witnesses described between them was a place where objects stop being objects. Then it broke for ten minutes, came back, and spent the rest of the day on the opposite kind of evidence: a phone that wrote everything down and kept it. The morning was about an absence. The afternoon was about a record. Both halves belong to the same case, and the order they arrived in is most of what made the day feel the way it did.

Before any of that, the posture, because this trial does not look like the ones you are used to watching.

Kosowski is a plastic surgeon. He was the plaintiff in a civil lawsuit, suing for money, and Cozzi was the attorney on the other side, defending the people Kosowski had sued. That lawsuit was going badly for Kosowski. A motion that would have ended it against him was set to be heard on May 2, 2023, and he had never filed a response to it. Cozzi disappeared six weeks before that hearing.

Kosowski has been in custody since March 25, 2023. He has gone through four defense teams and now represents himself. Standby counsel sit near him but they are not counsel of record and they do not speak for him. And he has waived a jury, for the guilt phase and for the penalty phase both. There is no jury in this case at any stage. Judge Joseph A. Bulone of the Pinellas Circuit is the only finder of fact there is. Every objection, every motion, every piece of evidence a lawyer would normally fight to keep away from twelve strangers goes into the head of the one person who decides the whole thing.

He is presumed innocent. Nothing below has been proven and nothing here says otherwise. What follows is what six witnesses said under oath on Friday, and what I think you should watch as it plays out.

The smell that would not compact

The State called a Waste Management route driver first. He has driven out of Naples since 2017, and in March 2023 he ran a front-load truck on a Thursday route that took him from Everglades City up the East Trail almost to the Dade County line. Somewhere in the middle of that run there is a dumpster at Monroe Station, off US-41 and down a dirt track he calls Loop Road. He hit it most Thursdays between roughly nine thirty and ten thirty in the morning. It served a dirt-bike and quad trailer park nearby, so what came out of it was household garbage. White kitchen bags. Paper plates.

The State asked the court to take judicial notice that March 23, 2023 was a Thursday. Kosowski agreed it was. That is a small, dry moment and it is worth understanding, because judicial notice is just the court accepting a fact that is not really in dispute, like a calendar date, without making anybody prove it. When a defendant agrees to it, he is saving everyone an hour. It also means the date is now locked in, and he cannot take it back later.

The pickup itself was nothing. The smell was something.

"It was uh it was a really terrible smell coming from the garbage I had just picked up," the driver testified. He hauls containers that hold dead animals. He said this was worse than those. When law enforcement came to him about it later he gave them a two-word version of his opinion that I am not going to type on this page, and he repeated it to the court without softening it.

Here is the part I would circle. He compacts roughly two hundred times in a day, and compacting normally buries a smell, because the smell is coming from air trapped in the load and you crush the air out. He compacted more than his usual count that morning because of how bad it was, and it did not work. That is a driver with seven years on the route telling the court that the thing in his hopper did not behave like garbage.

The State then put in a pre-marked exhibit with no objection from Kosowski: dashcam video of that morning's pickup, and a still frame of the hopper. The driver stood at the screen and narrated it. The container that normally held white kitchen bags held something else that day. "Big black bags like uh construction bags," he said. And the bags fell wrong. One on the far left of the frame dropped light, the way he expects. One in the middle did not. Asked what he had noticed, he said, "The weight on the bags."

He also described a screenshot from a week or two before March 23, a red Toyota Corolla parked empty in the spot where he normally pulls in, blocking his approach. He could not put a date on it. Hold that detail. A red Corolla comes back late in the afternoon session from a completely different direction.

Then the State passed the witness, and Kosowski said he had no questions. The driver stepped down.

Eight days later, it smelled like a normal dumpster

The second witness was a senior crime scene investigator with the Collier County Sheriff's Office, twenty-one years with the agency. On March 31, 2023 she was sent out to the Loop Road site at the request of the Largo Police Department, which wanted that dumpster processed for a victim's body or anything of evidentiary value in a Largo homicide. She got there at 11:08 in the morning and found a scene several agencies were already working. There was a cadaver dog on site. She watched it work and she watched it alert. Her recollection was that the dog sat down, or laid down.

Then the State asked her what the dumpster was like, and she gave the answer that the State is going to be living with for the rest of this trial.

Her photographs and video went in as an exhibit: the dog and its handler, a dirt spur running out to a sand-and-gravel pit, off-road trails, and a parking pad where a large truck had been parked at some point. She emptied the container herself and handed the contents to Largo detectives. The bags were not heavy. She did not recall any struggle lifting them, and she made the point that a struggle is exactly the kind of thing that gets written down at a scene, so if it had happened it would be in the paperwork.

Then she was asked whether everyone working that site understood the can had been emptied twice since the period that mattered. Her answer was that she was not made aware of how many times it had been emptied.

Sit with that for a second, because it is the single most important sentence of the morning. March 23 is when the driver hauled a load he could not stand to be near. March 31 is when she opened the can. Eight days. At least two pickups in between, and she was not told how many. Whatever she photographed, weighed and swabbed on March 31 may have no relationship at all to what left that site on the 23rd. The State did not hide this. The State elicited it.

The rest of her dumpster work was careful and undramatic. A carabiner held the chain, but there was no lock on it, and both doors opened. She measured the northwest corner at about five feet six inches and the door opening at thirty to thirty-one inches off the ground, which are the measurements you take when somebody is eventually going to argue about whether a person could get something up and over the lip. She ran presumptive blood testing on suspect areas. She noted heavy rust inside.

Seventeen feet down, three days, and every bone an animal

The next morning she was at the Collier County landfill at 8:35. A Largo detective sergeant told her Waste Management had worked out where the Monroe Station load would have ended up inside the fill. A multi-agency team gridded an area of roughly fifty feet by fifty feet and went down seventeen feet.

She was lead forensic processor for all three days of it, April 1 through April 3, and between the dumpster and the landfill she took more than 1,200 photographs.

The conditions in her testimony are worth repeating because they are what this kind of search actually costs. The dumpster site read 84.2 degrees on the first day, and excavation put another ten to fifteen degrees on top of that, because a landfill generates its own heat. Fog on the third morning. And the smell down in the cell, which she described this way: "That's a smell I won't forget." She put it somewhere between rotten eggs and a chemical.

Every suspected bone that came out of that grid went to the District 20 Medical Examiner. She described one item that looked, in her words, almost like a completed roast. Every single one came back the same way. Her summary of it was flat: you find a bone, you drive it in, and they tell you this is some sort of animal bone.

Partway through, the method changed. Layer-by-layer hand work became equipment pulling larger sections out to be searched, which is what you do when you are running out of daylight and out of days. They brought in the actual Waste Management truck on the last day and she found nothing remarkable about it. The search was discontinued around 5:30 in the afternoon on April 3.

The last question the State asked her on direct was whether she personally observed anyone collect human remains. She said no.

Kosowski had no questions for her either.

The man who runs the landfill answers a question nobody asked him

The third witness of the morning was a Waste Management district manager, with the company since 2015 and responsible for the Collier County landfill. He was not asked a single question about this case. He was asked how a landfill works.

So he explained it. Lane markers. Fifteen feet of spacing between trucks on the tipping face. A daily cover that is half dirt and half mulch, with a sprayed-concrete alternative when they use it. A tracking grid that keeps only about a hundred feet by fifty feet of face open at any one time, which, as a side effect nobody designed, is the only reason investigators could narrow a search area at all. Material goes down in twelve-inch lifts, and then, as he put it, the compactor runs it over until you cannot tell what it is anymore. The compactor weighs somewhere around ninety thousand pounds and it does not stop.

He ran an excavator himself during the recovery, and he set aside the first black bags and clothing items that came up so they could be gone through more carefully.

And then he was asked what he tells a new operator, and he answered the question this entire trial is asking without knowing that he had.

That is the day's line, and it is going to follow this case. It is also, and I want to be precise here, an honest answer to a fair question. The State is entitled to explain why a search came back empty. If a body went into that fill, the man who runs the fill is exactly the right person to tell the court what would be left of it. He was not shading anything. He was describing his job.

But there is a limit to what that buys the State, and the limit is simple. Explaining why you would not find something is not evidence that it was ever there. The landfill testimony makes the absence of remains consistent with the State's theory. It does not make the absence of remains evidence for the State's theory. Those are different things and a judge sitting as the finder of fact knows the difference better than anyone.

The State passed the witness. Kosowski declined to cross him too. The judge called a ten-minute recess.

Three witnesses, zero questions

Stop and count the morning. The driver who hauled the load: no cross. The investigator who processed the dumpster and led three days of digging: no cross. The manager who explained how the fill destroys what goes into it: no cross. Kosowski declined all three himself, out loud, on the record.

I want to be careful about what that does and does not mean, because this is where coverage of self-represented defendants usually goes wrong.

It does not mean he conceded anything. It does not mean the testimony is now proven. The State still carries the entire burden and an unchallenged witness is not a more truthful witness.

What it does mean, practically, is that the State's landfill chain went into the record in the shape the State built it, with nothing underneath it disturbed. And there was material there to work with. The investigator had already handed over the gap between March 23 and March 31 and the two unknown emptyings inside it. A lawyer would have taken that answer and turned it into ten minutes of daylight. Nobody did.

There is also a reading of it that is not a mistake at all. If your theory of the case is that the State never found anything, you may not want to spend an hour helping the State's witnesses explain the search in more detail. Sometimes the strongest thing you can do with an empty box is refuse to help anyone look inside it. I do not know which of those Kosowski was doing. Watch how he argues it at the end of the case and you will know.

A motion argued overnight, from a cell

When court came back, Kosowski asked to address the judge before the State called anyone. He wanted the DNA analyst's testimony from Day 4 struck from the record, and he apologized for the timing, saying the argument had come to him overnight.

His point was narrower and better than people expect from a defendant doing this himself. The analyst, he said, "really didn't provide his own interpretation of the results." He was reading numbers off a sheet produced by a computer program, and then reading that program's interpretation of those numbers. Kosowski said he had given the witness every opportunity to offer his own reading and the witness did not take it. Which leaves him, he argued, with testimony he cannot actually get at: "these aren't his own own words, and that I can't actually ask the computer program about how these results and these interpretations came to be."

That is a confrontation argument, and it is a live issue in courts around the country. The right to confront a witness assumes there is a witness to confront. When the substance of the opinion belongs to software and the human on the stand is relaying it, the question of who exactly you are cross-examining is not a silly one.

The State answered that the analyst had testified at length about his own expertise, personally performed the analysis, wrote the report himself, and used a standard database and a standard protocol, and that a protocol exists precisely so that results are standardized rather than improvised.

The judge denied it. He told Kosowski he was free to make every one of those points in closing argument, or to call his own witnesses and attack the findings that way, and then: "Obviously, uh you can do that, but I'm not gonna strike it at this time."

Watch that phrase, "at this time." It is not a door closing. In a bench trial it is a judge telling a defendant that the weight of the evidence is a question for the end, not the middle, which is a thing a judge can say to himself in a way he could never say to a jury.

There was one more piece of housekeeping and it matters more than it sounds. The State told the court it had given Kosowski a paper printout of the PowerPoint it planned to use with its next witness, noting that slides had been added since the original discovery answer back in May 2023 and that electronic copies had gone out along the way. A paper printout is what you hand a man who is defending a capital case from a jail cell. Remember that when we get to what he told the court he could not watch.

Presumptive means maybe

The State's next witness was its serologist, and I am going to write her by role rather than by name, which is how I am handling every witness in this case for now.

She spent nearly four years at the Pinellas County Forensic Laboratory, about two of them as a DNA technician and a little over two as a forensic serologist, holds a biochemistry degree, and completed a serology training module that ran roughly six months. She is now in her second year of medical school. The Largo submission reached her in March 2023 as a rush case with very little case information attached to it, and she explained that the lab prefers it that way, which is the right instinct: a bench scientist who knows the story tends to start seeing the story.

Her method was plain. Phenolphthalein as a presumptive color-change test, run with clean paper, fresh gloves and masks. Where an item's own coloring made the color change unreadable she switched to TMB. And here is the sentence to hold onto: her laboratory has no confirmatory test for blood at all. Whatever the presumptive result, she cut a sample from every item and sent it on for DNA analysis later.

Her results indicated blood on a Toyota tailgate swab, a garage swab, a men's bathroom floor drain, a marker on a bathroom floor, the most heavily stained of three napkins, and a latent photo area. Negative on the tailgate handle, other garage swabs, a trunk lid and a back wall, a north wall and a lobby door, the interior of the dumpster, and a driver-side front floorboard. Three items were not tested at all because the staining was too limited for serology to do anything with. She did nothing beyond what the request form asked her for.

Notice what the dumpster line does. The container that a cadaver dog alerted on, the container the driver could not stand to be near, came back negative on presumptive blood testing inside.

And understand what "presumptive" is doing in all of this. A presumptive test tells you a sample is worth testing further. It does not tell you that something is blood, it does not tell you whose it is, and in a laboratory with no confirmatory test the word never gets upgraded. Everything that turns those swabs into evidence about a person has to come from the DNA work done downstream, which is exactly the testimony Kosowski had tried to strike that morning and failed to.

Kosowski objected to her testimony as a product of the search warrant. The judge noted the objection and the questioning went on. She was not cross-examined in this stretch.

The detective, and the cameras that do not talk to each other

Then the State called the Largo Police Department detective who built its digital and video timeline, and the day changed shape completely.

He has been with Largo just over twenty-two years, working property crimes and then Crimes Against Persons before moving into cyber crimes in December 2020. Master's in cybersecurity from USF, a graduate certificate in digital forensics, IACIS training, and by his own count at least a hundred device examinations. An FBI special agent peer-reviewed the location analysis with him.

He got into the case on March 21, 2023, at the law firm itself. He pulled external video from a veterinary clinic next door. A transit bus camera at a Circle K gave him something a video investigator will tell you is worth more than resolution: a fixed, reliable clock. Working backward from that known time, he found a Toyota Tundra heading north on Belcher Road with a cart in the bed under a reddish cover. From there the team leapfrogged camera to camera across the county, including one belonging to a neighbor of Kosowski's, and by March 23 they had a search warrant.

Largo had no jurisdiction where the residence sat, so another department and the Sheriff's Office executed the warrant while he observed, entering in the small hours of March 24 and clearing out around six in the morning. Kosowski's phone number came to them, of all places, from his participation in a telephone court conference on March 21. T-Mobile records were obtained by court order on an exigency basis. He was stopped on March 25, and the detective described getting a body warrant the old-fashioned way, driving it out to a judge's house to be signed and sealed, because the new electronic warrant system did not yet carry that type.

An iPhone 12 Pro Max and a TracFone came out of the Corolla and went into Faraday bags, which are just shielded pouches that stop a phone from talking to a network and being wiped remotely. The TracFone was brute-forced, and the passcode that opened it also opened the iPhone, which allowed a full file system extraction. The TracFone itself held nothing of interest. The iCloud return arrived on April 21.

Everything he offered went in over a standing objection tied back to the search warrant, and the judge overruled it every time: the iCloud return, the phone extraction, a movement video, and the PowerPoint timeline.

In the middle of that, Kosowski told the court something quiet that I have not stopped thinking about. Asked about material he had been given, he said: "Oh we can't see MP4 is in the jail."

He cannot watch the video. The State's case, on Day 5, was mostly video. He is defending himself against the death penalty and he is doing it off paper printouts of frames other people selected. The judge moved things along. As of the close of Day 5 that problem is live and unresolved, and if you want one thing to watch on Tuesday, watch whether anybody solves it.

March 21, minute by minute

Through the timeline exhibit, the detective laid the State's case out in dates, and this is where you see what the State thinks happened.

A December 2022 text about buying the Tundra. In January 2023, a search for the victim's name and a search for the street address where he lived, seconds apart. In February, shopping for heavy-duty wheeled carts, a photograph of a vehicle at that same address, and searches for license plate flippers, which are the motorized frames that let a driver swap or hide a tag at the push of a button. In early March, property-record searches, and a search that put the victim's name together with his husband's name and the word wedding. Wi-Fi connections near the victim's street going back to January. Connections to the law firm's own guest network on March 7 and again on March 17. On March 14, the phone sitting locked at home while a dark-rimmed truck went past the firm.

And in the early hours of March 20, between roughly 3:06 and 3:14 in the morning, Firefox searches on succinylcholine, including a medical journal article about the dangers of giving it as an intramuscular injection.

Then March 21 itself, hour by hour.

At 7:51 a neighbor's camera catches the Tundra going southbound with the bed covered. At 8:08 the phone powers off, and it stays off until about 10:24. At 8:37 Cozzi arrives at work. At 9:50 he opens his office door to use the restroom, which is the last ordinary thing anybody has him doing. At 10:22 a figure leaves pulling a weighted wheeled item. At 10:27 a call goes to the court hearing line off a cell tower beside the firm, and the device does not move during that call. Around 11:04 the phone powers off again. By 11:05 video shows the wagon repositioned by the truck, with someone in the bed.

At 11:25 a bus camera at Belcher and Gulf to Bay catches the Tundra heading north, and this is the frame the State has been building toward all afternoon. Describing the item in the truck bed, the detective told the court it had the silhouette of a body.

At 11:51 a Flock camera further north catches the truck again with the load unsecured, and its New Jersey plate comes back to a Volvo registered, the detective said, to a deceased woman. Nobody explained that on Day 5. It just sat there. Later stills track the truck toward a dead-end street.

The phone's own afternoon

After the break the detective kept going through March 21, now from inside the phone rather than from cameras.

The device powered on at 12:02 in the afternoon, which he placed just after video of the Tundra heading toward the house. It joined the home network at 12:03 and stayed on it until 4:48. The first outgoing message went out at 12:03:42, a friendly hello to a personal contact. Then the phone sat locked for about two and a half hours. At 2:34 a work text came in about the next day's surgical schedule, and the reply dealt with timing and with not having a surgical assistant. Another message said he was heading back to Miami and would pick something up next time.

The phone locked again from 4:40 to 5:02. A neighbor's camera shows the red Corolla leaving at 4:48, coming back briefly, and leaving again at 4:56.

Then a 5:48 cell hit puts the device at the law firm, and the detective did something on direct that I want to give him credit for: he explained it against his own side's interest before anyone asked him to. He was personally at that scene at that hour, he said, along with numerous detectives and marked units. That ping is police presence. It is not the defendant. A witness who volunteers the innocent explanation for his own data point is a witness worth listening to on the rest of it.

From there, toll and plate-reader data follow the Corolla south. Across the Sunshine Skyway at 6:29. Paying the Alligator Alley toll at 8:38. Logged at the Florida 29 junction at 9:15. Then timing-advance data put the device at the Tamiami Trail and Loop Road for what he called a very short duration stop, which he estimated at somewhere between one and three minutes, with a plate-reader hit at 9:36 offered as corroboration.

Loop Road. The dirt track with the dumpster on it. On the night of the day Cozzi disappeared.

Then media logs show a Beatles track playing through CarPlay from 10:34 to 10:39, and the detective tied that back to the Beatles books and pictures he had seen in the house. The phone joined the rental home's Wi-Fi at 10:41 and stayed on it until 5:09 the next morning.

Two days later, an hour out and an hour straight back

On March 23, officers were staked out waiting for Kosowski to come back to a location. Instead the plate reader caught his tag heading west, and the cell data showed a drive of roughly an hour each way, out to the same Loop Road area where a dumpster would be searched eight days later.

The detective's description of the trip was the flattest sentence of the day: "No, it was appeared to be literally a drive there and then a turnaround and a drive back."

A text exchange with a physician contact at 9:04 that evening falls inside the window, and by 9:09 the phone is back at the rental.

March 23 is also the Thursday the driver emptied that dumpster in the morning.

He also testified about how he got to Monroe Station in the first place, and it is a genuinely good piece of police work. He reviewed the timing-advance data on March 30. It stood out to him. He played it over and over and told his sergeant there had to be something out there. They drove out that night, in the dark, through brush, with alligators moving in the water nearby, and found a dumpster secured with a carabiner. Inside were a couple of small bags of trash.

The direct also covered a plate flipper found on the truck, which lands back on those February searches for exactly that device. Searches on March 25 for the Largo Police Department and for a Largo police warrant, made while Kosowski was still in Miami, followed that afternoon by the traffic stop, a plate flipper on the Corolla as well, and photographs showing a firearm and a bag on the passenger seat.

He explained timing advance itself, which is worth understanding because a lot of the State's map rests on it. Timing advance is a measure of how far a device sits from a tower, derived from how long the signal takes to make the trip. It gives you a distance, not a direction, and the confidence band around that distance gets worse the further out you go. He said plate-reader data was used to shore up the gaps. Mapping software showed the device going silent through the morning power-off window and reappearing at about 12:02, and showed the evening route south including a westbound leg that ran right past the law firm. The State called that leg a diversion on the way to Miami.

On the landfill, he said he learned on March 31 that the dumpster had been emptied on the 23rd. Landfill video showed a large bag hitting the pile and the trash around it giving way, and he gave the court his reading of it: the way the items slumped "would have been to me suggestive or indicative of a body being within that bag." He said the sergeant reported the cadaver dog's positive alert on the dumpster. He was present for the first day of the dig.

Then came the closing questions on direct, and they cut both ways, which is what an honest direct examination looks like near the end. Nothing belonging to Cozzi was ever recovered, despite roughly five agencies searching. Cozzi's phone was left at his desk. His watch, which paired by Bluetooth and nothing else, has never been found. And asked what the dealings between the two men appeared to be, the detective answered: "No, everything appeared to be uh business related."

The one thing the defendant took, and he took it himself

Then Kosowski cross-examined him. It is the only cross-examination he conducted all day, and for about ten minutes he was good at it.

He started with the phone, and he started from the device's own activity database rather than from a theory. He got the detective to agree that locked means only that the phone is locked and not being used. He got him to agree that the Corolla leaving Wi-Fi range would not unlock the device. Those are small concessions and they are real ones, and they point at something the State needs you not to think about too hard: the power-off windows and the locked windows are facts about a phone. They are not facts about a man. A phone in a drawer looks exactly like a phone whose owner is being careful.

Then he went at the Loop Road stop, and this is the moment on Day 5 where the defendant drew blood.

The State's own position was that the device was at Loop Road at 9:34. The State's own plate reader logged the car a few miles up the road at 9:36. Kosowski did the arithmetic out loud in open court. Two minutes to cover that distance works out to something like sixty miles an hour with no stopping in it at all. So where, he wanted to know, is the one to three minute stop?

The detective did not retreat, and he did not really answer either.

That is not an answer to arithmetic. It is a witness standing on his estimate. And the estimate matters enormously, because the one to three minute stop is the only thing in this entire timeline that puts Kosowski's car actually at the dumpster site on March 21. Take the stop away and what you have left is a car driving past a turn on the way to Miami.

He did not get to press it. His next line was, "You can't reason with you, can you?" The objection was sustained and the cross ended right there, which is a shame, because the question underneath it was the best one anybody asked all day.

On redirect the State repaired the smaller of the two points, getting the detective to confirm that a device stays connected to Wi-Fi as long as it remains in range. That takes care of the Wi-Fi argument. It does nothing at all about the timing.

So the arithmetic is still sitting there, open, and the State is the one who put it in the record.

The last witness, and the questions somebody had already asked

The State closed the day with an anesthesiologist. He has practiced since 1991, been board certified since 1994, owns a dental anesthesia practice in Tampa, holds privileges at Tampa General, ran resident education at USF for most of a decade, and has sat on the Florida Board of Medicine since 2016. He spelled his own name for the court, which is the kind of small courtesy that makes a court reporter's night.

He was asked about succinylcholine. He described a depolarizing muscle relaxant, a drug that produces complete paralysis and does nothing else at all. Then he said the sentence that is going to follow this case wherever it goes.

The heart keeps going. The muscles that move air do not. "Your breathing muscles are paralyzed, so you won't breathe," he testified, and without someone managing the airway the patient will "either die or or certainly suffer brain death." This is a drug anesthesiologists use constantly and safely, for the plain reason that in an operating room there is always somebody standing there breathing for you.

He examined a sealed vial in evidence, 200 milligrams per milliliter in a ten milliliter vial, along with an 18-gauge needle and a syringe. He noted that Florida rules require plastic surgery offices to keep the drug on hand, which cuts in an interesting direction: possession of it is not unusual for this defendant's profession, it is mandatory.

The State then put a hypothetical to him, and I want to be careful about how I report this, because a lawyer's question is not evidence. The State asked him to assume a person five foot ten and roughly 190 to 195 pounds who received an entire vial with nobody assisting their breathing. His answer was, "I would say it's very likely that it would be." He testified that a full vial means a minimum of eight minutes of immobility and more likely ten to fifteen, and that a smaller dose leaves a person limp within thirty to sixty seconds given by vein, or a minute to a minute and a half given into muscle, lasting five to ten minutes.

Nobody in that stretch of testimony connected that height and that weight to any actual person. The State put the numbers in the question. Whether it ever ties them to anyone is a thing you will find out later in this trial or not at all, and you should hold the hypothetical exactly that loosely until it happens.

The last thing he did before the day ran out was review the search links the detective had recovered and describe what they were actually about: onset of action, route of administration, whether the drug could be given intramuscularly, and how long it lasts.

That is the join the State came for. Before this witness, a set of three-in-the-morning searches was suspicious. After him, two witnesses who never spoke to each other have described the same four topics: the detective read them off a phone, and a physician independently identified them as the exact clinical questions that matter if you intend to paralyze someone. Neither one of them has to be believed on faith for that overlap to mean something.

He was still on direct, moving into the complications literature, when the day ended. There has been no cross of him. In this trial, that means Kosowski will do it himself, with no lawyer beside him and one judge listening.

What Day 5 actually did, and what it did not

The State carries the burden. No verdict has been returned and the State has not even rested. Here is where I think the day landed.

The morning went to the defense, and it went there on the State's own witnesses. Three days in a landfill. Five agencies. Seventeen feet down. More than 1,200 photographs. Everything that looked like bone came back animal. The investigator who processed the dumpster told the court it smelled like a normal dumpster and that the bags were not heavy, and she did not know how many times that container had been emptied in the eight days before she opened it. Nothing in the entire morning connected Kosowski to that dumpster or to anything in it. The State's answer, delivered by the landfill manager, is that you would not expect to find anything, and that answer is credible, and it is still an explanation rather than a fact.

The afternoon went to the State, and it was not close. The timeline is the strongest thing the State has put on in this trial, and its strength is not any single data point. It is that the data points come from systems that have no idea the others exist. Browser history. Wi-Fi association records. Cell tower timing. A transit authority's bus camera. A private veterinary clinic's DVR. A neighbor's doorbell. A plate reader. A toll transponder. CarPlay media logs. None of those systems coordinate, none of them were built for this, and they all point the same way.

What they point at is a phone searching a man's name and then his street address in January, shopping for a heavy wheeled cart in February, searching for plate flippers, connecting to his law firm's guest Wi-Fi twice in March, reading about a paralytic drug at three in the morning on March 20, and then going dark for the exact window on March 21 in which that man was last seen alive and a covered load left the building in a truck. Two days later the same phone drives an hour out to a dirt road and turns straight around.

Two pieces of it are interpretation rather than data, and they are the two that will get fought over. A phone being off is consistent with somebody hiding their movements and it is also consistent with a phone being off. And the thing in the truck bed is a shape on a low-resolution frame that a detective is telling the court has the silhouette of a body. That is his reading. A judge is free to look at the same frame and read it differently, and in a bench trial he will be looking at it himself.

The serology is weaker than the word makes it sound. Presumptive only, no confirmatory test available in the lab at all, and nothing in it tells anyone whose blood it might be. All of that weight transfers onto the DNA work, which is exactly the testimony Kosowski tried to knock out that morning and did not.

For the defense, Day 5 was mostly preservation. The motion to strike failed. The warrant objection was overruled on every single exhibit. Three witnesses walked off the stand without a question. He told the court he cannot open the State's own video from where he is being held, and nothing changed as a result. He kept his issues alive for an appeal that does not exist yet. He did not move the case.

Except once. The one to three minute stop at Loop Road is the only thread in that whole timeline that puts his car at the dumpster site on the day Cozzi vanished, and he stood up without a lawyer and showed the court that the State's own two data points describe a car doing sixty miles an hour past the turn instead of stopping at it. The detective called it an approximation and said he stands by it. That is now an open question in a capital case, and the man who opened it is the defendant.

What Tuesday has to answer

Court does not sit again until Tuesday, September 22 at 10:30 in the morning. The judge put on the record that Monday is a Florida Supreme Court mandated holiday.

Three witnesses were still technically on the stand when Day 5 ended. The serologist gave her direct and was never released, and the record leaves open that she may be recalled. The detective finished cross and redirect but was never released in words. The anesthesiologist was mid-testimony when the day ran out.

So here is what I am watching for.

Whether Kosowski goes back to the timing-advance arithmetic, because it is the one place he has already drawn blood and the State has not repaired it. Whether the State ever ties that hypothetical height and weight to a person, or leaves the number hanging where it is. Whether anyone in that courtroom solves the problem of a man defending his own life who cannot watch the video being used against him. And whether the State, having spent a morning explaining why there is nothing left to find, can close the distance between a phone that was in the right places and a person who was holding it.

That last one is the whole case. It always was.
