Steven Randall Cozzi, a 41-year-old Pinellas County attorney, disappeared after going to his office in Largo in March 2023. Coworkers noticed his sudden absence when personal items were left behind — his phone, wallet and keys — and his car remained parked at the Belcher Road office complex.

Investigators focused on the building’s common restroom and surveillance from the complex. Court filings and reporting describe significant blood evidence in and around the restroom and signs someone attempted to clean the scene. Surveillance footage and license-plate reader data are reported to show a person entering the building and later leaving with a heavily loaded large cart during the window when Cozzi vanished. Reporting based on investigative filings links a Pinellas County plastic surgeon, Dr. Tomasz Kosowski, to movements around the building and to items investigators say were consistent with restraints, weapon-like objects and injectable drugs; authorities have said they believe Cozzi was killed and charged the suspect with first-degree murder.

Co-workers and the community have held gatherings in support while the family endures the added pain that no body has been recovered. Does anyone have information about Steven’s movements in Largo that day or about unusual activity around the Belcher Road office complex?
