Tomasz Kosowski built an Ivy League medical career before police say he murdered the lawyer suing him.
Kosowski fired his lawyers and chose to defend himself against a possible execution.
What Kosowski did with that choice should terrify anyone who thinks they are smarter than a courtroom.
Kosowski Fired His Lawyers to Take on a Death Penalty Case Alone
Tomasz Kosowski, 47, is a plastic surgeon from the Clearwater area facing a first-degree murder charge in the disappearance of attorney Steven Cozzi, 41.
Cozzi vanished in March 2023 while representing the opposing side in a medical billing lawsuit Kosowski had filed.
Investigators say they found blood inside Kosowski's pickup truck and told jurors he had assembled a kit containing a Guy Fawkes mask, stun guns, duct tape, and trash bags.
Cozzi's body has never been found.
Kosowski dismissed the attorneys assigned to defend his life and told the court he would handle a capital murder trial by himself.
Judge Bulone pressed him directly at an August 21 hearing, asking, "You understand that they're experts in death penalty law?"
Kosowski said he understood and pushed forward anyway.
He Struck the Defense That Could Have Saved His Life Without Realizing It
Kosowski's prior attorneys had filed motions specifically fighting the death penalty prosecutors are seeking against him.
At the August hearing, Kosowski withdrew every one of those motions himself, telling the judge, "I move that we strike them all."
A defendant facing execution just voted to remove the one legal shield standing between him and a needle, and the judge let the record show he did it with his eyes open.
Kosowski has fared no better on the evidence.
He argued that investigators broke the chain of custody transporting his truck, telling the court, "Nobody followed the truck on the way to the processing garage."
He cannot file documents electronically from jail, so his mother has been hand-delivering his paperwork to the courthouse instead.
Jury selection began September 14, and Kosowski is still deciding whether he wants a jury or a judge to decide whether he lives.
Kosowski Asked a Prosecutor to Climb Into a Trash Bag in Front of the Jury
Prosecutors allege Kosowski killed Cozzi and disposed of his body in trash bags, and part of their case rested on how much a bag like the ones found in his truck could actually hold.
Kosowski disagreed with the size prosecutors were suggesting, so on September 16 he turned to prosecutor Nathan Vonderheide during cross-examination and asked him directly, "Can you step into the trash bag for us?"
Vonderheide told the court he did not understand what Kosowski was asking him to do.
Judge Bulone denied the request outright and noted Vonderheide had no obligation to answer it.
Kosowski never went back to cross-examine the forensic analyst who had testified about the bags in the first place.
A man on trial for his life just asked the man trying to execute him to physically climb inside the evidence, live, in front of the jury deciding his fate.
Self-Representation Almost Never Works and History Proves It Every Time
Colin Ferguson fired his lawyers after opening fire on a Long Island Rail Road train in December 1993, then told jurors at trial that a phantom gunman did it despite twenty-four eyewitnesses.
He got two hundred years in 1995.
Jack Kevorkian beat two assisted-suicide cases with lawyers, then fired his attorney and represented himself on the third.
He was convicted and sentenced to ten to twenty-five years.
Fox News judicial analyst Andrew Napolitano called D.C.-area sniper John Allen Muhammad "a dope" for making the same choice, warning that judges "have to bend over backwards to make sure both sides get a fair trial, otherwise the conviction could be meaningless."
Kosowski has an Ivy League education, a medical license, and a courtroom full of prosecutors who do this for a living and nothing else.
He is learning in real time that none of the first two matter against the third.
None of it required a defense attorney to point out, because Kosowski did it to himself on the record, in open court, in front of the judge who begged him to reconsider.
