Steven Randall Cozzi, a 41-year-old attorney based in Pinellas County, disappeared after going to work in Largo in March 2023. He was employed at a law firm in an office complex along Belcher Road. When concern grew over his sudden absence, coworkers and investigators focused on the fact that personal essentials were left behind, including his phone, wallet, and keys, and his vehicle remained at the building.
Early information released by local reporting described the circumstances as suspicious, with investigators initially holding back details while they worked leads.
As authorities pieced together what happened, the investigation centered on the office building’s common restroom area and surveillance footage from the complex. Court documents and reporting based on those filings describe signs of significant blood evidence in and around the restroom, along with indications that someone attempted to clean the scene. Surveillance review also became a critical thread: investigators described a person entering the building and later leaving with a large cart that appeared heavily loaded, a sequence that prosecutors would later argue aligned with the window in which Cozzi vanished.
Attention soon narrowed to a Pinellas County plastic surgeon, Dr. Tomasz Kosowski, who had been involved in contentious legal conflict tied to Cozzi’s work. Reporting drawing from affidavits and subsequent court filings describes how investigators connected the suspect to the office complex and to key movements afterward using surveillance and license-plate reader data. Authorities have alleged that Cozzi was killed inside the office building shortly after a legal proceeding connected to that dispute, and that his body was removed and transported away from Largo.
Investigators have publicly outlined a disturbing collection of physical and forensic findings they say support the homicide allegation. Reports based on arrest paperwork describe blood evidence associated with the suspect’s vehicles, along with items investigators characterized as tools consistent with abduction or violence, including restraints and weapon-like objects. Court-filings-based reporting has also referenced injectable drugs and medical paralytics among the materials tied to the suspect, alongside fiber and trace comparisons investigators say linked vehicles and locations involved in the case.
From the family’s perspective, the case has carried a uniquely painful limbo: the loss is treated by authorities as a homicide, yet the absence of a recovered body leaves loved ones without the most basic, human certainty and the ability to lay him to rest. Community members and colleagues organized gatherings of support as the legal system moved forward, remembering Cozzi as a valued member of the legal community while also grappling with the shock of a disappearance that unfolded in an ordinary workday setting.
Based on publicly available reporting, this is not considered an active missing-person search in the usual sense. Authorities have stated they believe Steven Cozzi was killed, and Dr. Kosowski has been charged with first-degree murder; prosecutors have also pursued the case at the highest level of severity. At the same time, reports continue to note the central unresolved heartbreak: Cozzi’s body has not been found, leaving an enduring gap for the people who loved him and for a community still waiting for the fullest measure of answers.Last Seen: Mar 21, 2023
