Criminal Mischief

THE MURDER OF STEVEN COZZI The Tomasz Kosowski Case When attorney Steven Cozzi arrived for work at his Largo, Florida, law office in March 2023, there was little reason to believe he wouldn't be going home that evening. Then he vanished. His wallet, phone and keys were left behind. Investigators found blood inside the men's restroom at the law firm, but there was no sign of Cozzi himself. His body has never been recovered. What followed was an extraordinary murder investigation that eventually led authorities to Dr. Tomasz Kosowski, a plastic surgeon locked in a bitter legal dispute involving the medical practice where he had once worked. Cozzi represented defendants in that litigation, and prosecutors argued that Kosowski's anger over the case had become an obsession. The evidence investigators assembled told a chilling story: surveillance footage, forensic evidence, movements before and after Cozzi disappeared, and a trail prosecutors said connected Kosowski directly to the attorney's death—even without a body. But the case took another remarkable turn when Kosowski went to trial for first-degree murder and made a decision that dramatically raised the stakes: He represented himself. Facing the possibility of a death sentence, Kosowski questioned witnesses, challenged evidence and personally attempted to convince the court that prosecutors had accused the wrong man. It didn't work. In September 2026, Kosowski was found guilty of first-degree murder in the death of Steven Cozzi. This week on Criminal Mischief, Carolyn Ossorio takes us inside the disappearance of Steven Cozzi, the evidence that transformed a missing-person investigation into a murder case, the bitter legal conflict prosecutors said supplied a motive, and the extraordinary spectacle of an accused killer attempting to defend himself against a case that could ultimately cost him his life. And at the center of it all remains one haunting unanswered question: Where is Steven Cozzi?

CRIMINAL MISCHIEF Inside COLD Season 4: Blamed on Bundy — with Dave Cawley This week, Carolyn Ossorio sits down with investigative journalist Dave Cawley, creator and host of KSL’s acclaimed true-crime podcast COLD, to talk about its newly released fourth season: Blamed on Bundy: The Disappearance of Nancy Baird. Cawley has spent more than two decades covering courts, crime and missing-person cases, and COLD has become known for taking a single disappearance and investigating it with extraordinary depth. Season Four takes listeners back to 1975 and the disappearance of Nancy Baird from a gas station in Layton, Utah. Over the years, suspicion became entangled with the most infamous name in American serial murder: Ted Bundy. But Bundy denied responsibility, and Cawley’s new investigation asks whether attaching his name to Nancy’s disappearance actually brought investigators closer to the truth—or helped obscure it. Carolyn and Dave go behind the production of Blamed on Bundy to discuss what it takes to reopen a decades-old mystery, how investigators separate evidence from assumptions, and the peculiar gravitational pull Bundy continues to exert over unsolved cases half a century later. They also explore the responsibility true-crime storytellers have to the missing women at the center of these stories, particularly when the celebrity of a suspected killer threatens to become more famous than the victim whose fate remains unknown. COLD: Season 4 — Blamed on Bundy: The Disappearance of Nancy Baird is now in wide release from KSL Podcasts (https://kslpodcasts.com/?utm_source=chatgpt.com).

Then listen to COLD Season Four and decide for yourself: was Nancy Baird really another victim of Ted Bundy—or has everyone been looking in the wrong direction for fifty years?
