Florida plastic surgeon Tomasz Kosowski faces bench trial in alleged lawyer murder
Former Florida plastic surgeon Tomasz Kosowski is on trial in Pinellas County for the presumed 2023 killing of attorney Steven Cozzi. The case stands out because Kosowski waived a jury, is representing himself, and faces the death penalty in a no-body homicide prosecution.

A capital murder trial is now underway in Pinellas County, Florida, where former plastic surgeon Tomasz Roman Kosowski is accused of killing Largo attorney Steven Cozzi in March 2023. According to the pending first-degree murder case, Kosowski has pleaded not guilty, waived a jury trial, and is representing himself while the State of Florida seeks the death penalty.
The case has drawn unusual attention because prosecutors are pursuing a murder conviction without recovered remains. Reporting from the opening days of the Pinellas County trial indicates the state alleges Kosowski killed Cozzi inside the bathroom of the Blanchard Law office in Largo, moved his body using a wagon, and later disposed of it in a dumpster.
Background On The Case
Cozzi disappeared on March 21, 2023, after a scheduled workday at the Largo law firm where he practiced. Prosecutors have long alleged that Kosowski targeted Cozzi because the attorney was involved in civil litigation connected to Kosowski’s dispute with former colleagues and business associates. According to the indictment and charging history, Kosowski was arrested in March 2023 and later indicted for first-degree murder by a Pinellas County grand jury.
Coverage from Tampa Bay Times and local television has described the state’s theory as a heavily circumstantial but detailed timeline case. In the state’s opening presentation at trial, prosecutors outlined surveillance evidence, forensic evidence, and Kosowski’s alleged movements before and after Cozzi vanished. WFLA likewise reported that the trial began this week in Pinellas County, with the state presenting a no-body homicide case to a judge rather than a jury.
That procedural posture is one reason the trial stands out. The Pinellas docket reflects an order granting a bench trial for both guilt and penalty phases on August 31, 2026, and later entries show the court continuing to find Kosowski competent to waive counsel during a September 14 Faretta hearing. Tampa Bay Times also reported in pretrial coverage of the upcoming murder case that Kosowski chose to act as his own lawyer despite the capital stakes.
Why A Bench Trial Matters In A Death Penalty Case
In Florida criminal cases, a defendant can waive a jury trial under Rule 3.260 of the Florida Rules of Criminal Procedure, allowing the judge to decide guilt in what is commonly called a bench trial. Public docket entries in this case indicate the court accepted that waiver and also permitted Kosowski to proceed without counsel after repeated competency findings tied to his self-representation. The court’s recent Faretta-related docket entries are especially significant because self-representation in a capital case often triggers close judicial review.
In general terms, a bench trial changes the courtroom dynamic. There is no jury selection, no need to simplify evidence for twelve lay jurors, and fewer concerns about emotional spillover from especially graphic or unusual allegations. A judge may focus more tightly on evidentiary detail, procedural objections, and the internal consistency of the state’s timeline.
That does not make the state’s burden lighter. Prosecutors still have to prove guilt beyond a reasonable doubt. In a no-body homicide case, that usually means the prosecution leans heavily on forensic evidence, digital evidence, surveillance footage, motive evidence, and post-disappearance conduct. Court TV’s trial coverage described a case built around missing remains, forensic proof, and self-representation, which tracks the outline reported by local outlets covering the same proceedings.
The State’s Theory Without A Body
Florida prosecutors do not have to produce a victim’s body to obtain a murder conviction. But as a practical matter, those prosecutions often receive closer scrutiny because the state has to establish both death and criminal agency through indirect evidence.
According to the live trial updates from September 17, 2026, prosecutors told the court they believe Cozzi was killed in the office bathroom and then removed from the building in a wagon before being discarded elsewhere. Earlier reporting on the start of the trial described surveillance footage and blood evidence as major components of the state’s case.
That kind of evidence can be powerful, but it also tends to invite detailed fights over inference. A defense in a circumstantial case may focus on whether the timeline leaves room for alternative explanations, whether the forensic interpretation is overstated, whether investigators ruled out other possibilities, and whether motive evidence is being used to fill gaps in direct proof. Because Kosowski is representing himself, many observers are also watching how much adversarial testing the prosecution’s case will actually receive in real time. Court TV reported during this week’s proceedings that Kosowski complained about limits on access to trial materials while acting pro se, underscoring the practical complications of self-representation from custody.
What The Death Penalty Adds
This is not just a murder trial. It is a capital trial, which raises the stakes dramatically. The Pinellas docket includes multiple filings challenging Florida’s death penalty framework and aggravating factors, showing how much pretrial litigation focused on sentencing issues even before testimony began.
That matters for two reasons. First, every phase of a capital case tends to be litigated more aggressively, including competency, waiver of counsel, evidentiary issues, and jury-related rights. Second, any conviction in a death-eligible case often generates years of post-trial litigation about procedure, constitutional safeguards, and the adequacy of the record.
In a bench trial setting, those appellate questions can become even more pointed. A reviewing court may later look closely at whether the waiver of jury trial was knowing and voluntary, whether self-representation was valid under Faretta principles, whether standby counsel’s role was adequate, and whether the trial court’s findings were supported by competent evidence. That is one reason legal observers often pay attention not only to verdicts, but also to how the record is built day by day.
What This Case May Mean For Affected Parties
For families, colleagues, and anyone following the case, this trial is likely to be emotionally difficult because it proceeds without the recovery of Cozzi’s remains. In many no-body prosecutions, that absence can leave a case feeling unresolved even if a conviction follows. For prosecutors, the challenge is turning fragmented evidence into a coherent narrative. For defendants, the challenge often centers on whether the state’s narrative is the only reasonable one.
For lawyers and court watchers, the case also highlights the tension between constitutional autonomy and courtroom practicality. A defendant has the right, in some circumstances, to reject counsel and conduct his own defense. But when that happens in a death penalty case, the result can look less like a conventional adversarial trial and more like a judicial stress test of due process.
The story also fits into a broader pattern of high-profile homicide cases built on circumstantial evidence, unusual procedural choices, and intense public scrutiny. Readers who follow these kinds of prosecutions may also recognize echoes of other recent cases involving disturbing allegations in a Philadelphia homicide investigation, where attention quickly shifted from the headline accusation to the quality of the evidence and the legal process around it.
What Affected Parties Might Consider
For people who see aspects of their own lives in this case, the legal issues can feel broader than the headline. Workplace disputes, stalking allegations, missing-person investigations, wrongful death concerns, and criminal exposure tied to digital or surveillance evidence can all escalate quickly once law enforcement or prosecutors become involved.
In general terms, cases like this often turn on documented timelines, preserved communications, forensic interpretation, and procedural strategy. Families seeking answers, witnesses contacted by investigators, and individuals facing serious allegations may want to consider how early legal guidance can shape evidence preservation, interviews, motion practice, and long-term case positioning. An attorney might also help determine how a case’s public narrative differs from what the court record can actually prove.
