The episode details the four-decade investigation into the 1982 murder of Lee Rotatori, a dietician discovered dead in an Iowa motel. Although the victim's husband, Jerry Nemke, was a convicted murderer with a suspicious background, his ironclad alibi initially shielded him from being charged. The case remained unsolved until recent advancements in genetic genealogy allowed investigators and a volunteer researcher to identify Thomas Oscar Freeman as the killer through DNA evidence. Further inquiries revealed that Freeman was likely a hired hitman connected to Nemke through their shared prison history and suspicious phone calls. Ultimately, the investigation concluded that while Freeman committed the act, he was murdered shortly after the crime, potentially by the husband who orchestrated the plot.
