A Florida plastic surgeon was found guilty of murdering a lawyer whose body was never found.

Tomasz Kosowski was charged with first-degree murder in the death of Steven Cozzi, who disappeared in March 2023.

Prosecutors said Kosowski had a "malicious and personal obsession" with Cozzi, who was representing defendants sued by Kosowski when he went missing from his law firm, and "methodically and systematically" planned the murder.

Judge Joseph Bulone found Kosowski guilty following closing arguments Wednesday. Kosowski, who represented himself in the case, had waived his right to a jury trial.

The penalty phase of the trial will begin Wednesday afternoon, during which the judge is set to hear arguments on aggravating factors.

Kosowski also waived his right to counsel and a jury for the penalty phase. He faces a sentence of life without the possibility of parole or the death penalty.

The state is seeking the death penalty.
