Story summary

Tomasz Kosowski, a 47-year-old plastic surgeon educated at Dartmouth Medical School, is facing a death penalty trial in Pinellas County, Florida for the murder of attorney Steven Cozzi. In March 2023, Cozzi disappeared after dealing with legal matters involving Kosowski. Prosecutors allege that Kosowski killed Cozzi in his office bathroom and disposed of the body in a dumpster near Alligator Alley highway.

Kosowski, who has chosen to represent himself pro se and waived his right to a jury trial, is now standing trial before Judge Joseph Bulone. During one court hearing, he made a bizarre remark about prosecutor Nathan Vonderheide stepping into a trash bag, questioning the relevance of forensic analysis involving capacity. This unusual behavior continued as Kosowski dismissed several attorneys and public defenders from his case.

The prosecution’s evidence includes blood found in Kosowski's Toyota Tundra, discovered during a search warrant execution at his home two days after Cozzi’s disappearance. Despite this damning evidence, Kosowski maintains his innocence throughout the trial proceedings.
