A Pinellas County judge found Florida plastic surgeon Tomasz Kosowski guilty of first-degree murder on September 23, 2026, after a bench trial in Clearwater over the 2023 disappearance and death of attorney Steven Cozzi. According to the first-degree murder verdict in Judge Joseph Bulone’s courtroom, the case ended without a recovered body but with prosecutors relying on forensic, surveillance, cellphone, and other digital evidence.
The ruling followed about a week of testimony in a closely watched case that had already drawn attention because Kosowski represented himself and waived a jury. ABC News reported that the judge found Kosowski guilty following closing arguments, and that the case moved directly into a penalty phase in which he now faces either life in prison without parole or a death sentence.
What The Court Found
Prosecutors argued that Kosowski methodically planned Cozzi’s killing in connection with a bitter civil dispute, then carried it out inside the bathroom of Cozzi’s law office before removing the body from the building. According to the prosecution’s theory of a planned killing tied to the civil lawsuit, Cozzi had been representing defendants whom Kosowski had sued when he disappeared in March 2023.
Local reporting described a detailed evidentiary record. According to FOX 13, surveillance video, cellphone pings, and blood evidence placed intense focus on the law office, a Toyota Tundra, and Kosowski’s home and garage. Investigators reportedly found Cozzi’s blood in the law firm bathroom, inside the truck, on a garage floor, and in a vehicle Kosowski was driving when he was arrested.
That factual pattern mattered because this was a no-body homicide prosecution. Even without a recovered body, prosecutors can still attempt to prove death and criminal agency through circumstantial and forensic evidence. In practical terms, that often turns the case into a contest over whether the evidence fits one coherent explanation better than any innocent one. Here, the judge concluded the state had met that burden beyond a reasonable doubt, according to the guilty finding after seven days of testimony.
Why The Bench Trial Stood Out
One reason this case drew unusual public attention is that Kosowski waived both a jury trial and, later, counsel for the penalty phase. In other words, the judge acted as factfinder during guilt, rather than a panel of jurors. As covered in our earlier report on the bench trial decision, that procedural choice changed the texture of the trial from the start.
In a bench trial, the legal standard does not change. The prosecution still carries the burden of proving guilt beyond a reasonable doubt. But the presentation can look different because arguments aimed at a judge may be more tightly focused on evidentiary detail, chronology, and legal inferences than on emotional appeal. That appears to have been especially relevant in a case built on extensive forensic and digital evidence rather than eyewitness testimony to a killing.
Self-representation also added another layer of legal risk and complexity. Courts generally permit a criminal defendant to waive counsel if the waiver is knowing and voluntary, but those cases can become procedurally delicate, particularly when the charges are this serious and the death penalty remains on the table. Some people following this case may see the verdict as a reminder that representing oneself in a capital case can radically reshape trial strategy, witness handling, objections, and penalty-phase preparation.
The Missing Body Did Not End The Case
The absence of Cozzi’s body was central to the public narrative, but it was not necessarily fatal to the prosecution’s case. FOX 13 reported that investigators never recovered Steven Cozzi’s body, even after cellphone records led authorities toward a dumpster route and a Collier County landfill search.
That detail often matters emotionally for families and legally for jurors or judges weighing uncertainty. Still, homicide prosecutions do not automatically fail because remains are missing. If prosecutors can build a persuasive chain of circumstantial proof—physical evidence, digital location data, suspicious movements, motive evidence, and post-event conduct—the court may still find guilt. According to ABC News, the state characterized the killing as methodical and systematic, a framing consistent with a circumstantial case built piece by piece.
For families in similar cases, this kind of verdict can be legally significant even when it does not bring the same closure as a recovered body. A conviction may answer the criminal liability question while leaving major personal questions unresolved.
What Happens Next In Sentencing
The guilty verdict did not end the case. It moved the proceeding into a capital sentencing phase, where the court will weigh aggravating and mitigating circumstances under Florida’s capital sentencing statute. Under Florida law, when a defendant waives a sentencing jury, the court may impose either life imprisonment without parole or death after considering the aggravating and mitigating evidence.
ABC News reported that the judge found two alleged aggravating factors proved beyond a reasonable doubt: financial gain, and a killing committed in a cold, calculated, and premeditated manner. The judge reportedly did not find a third alleged factor—especially heinous, atrocious, or cruel—proved on the available record.
That matters because capital sentencing in Florida is not automatic after a first-degree murder conviction. The existence, number, and weight of aggravating factors can shape whether the court ultimately imposes death or life without parole. FOX 13 reported that a Spencer hearing is scheduled for October 8, 2026, where the court is expected to hear final penalty-phase arguments before sentencing at a later date.
For defendants and lawyers watching from the sidelines, the case may become a reference point in several areas at once: no-body murder prosecutions, the evidentiary force of digital records, and the strategic consequences of self-representation in a capital case. It also underscores how a civil dispute can evolve into evidence of motive in a criminal prosecution when prosecutors can connect the timeline, prior confrontations, and preparation evidence into one narrative.
And for anyone confronting a serious criminal investigation or a high-stakes wrongful death matter, this case is a reminder that outcomes often turn on very specific facts: what surveillance captured, where devices traveled, what forensic testing found, and how each piece fits with the broader record. In general terms, people facing similarly complex legal exposure may want to consider finding counsel with documented experience in highly similar matters, especially where digital forensics, homicide evidence, or penalty-phase issues are involved.
