Story summary

In 2019, Steven Cozzi, a lawyer in New Jersey, went missing under mysterious circumstances. The case eventually centered on Tomasz Kosowski, a plastic surgeon, who was charged with Cozzi's murder and represented himself during his trial. Prosecutors presented evidence including what they called a "murder bag" containing items used to commit the crime, as well as the use of a paralyzing agent that prevented Cozzi from defending himself. The case gained national attention due to its gruesome details, and Erin Moriarty of CBS's "48 Hours" reported on it extensively, highlighting how Kosowski's obsession with control ultimately led to his conviction for murder.
