Unlawful Acts

On Halloween night in 2004, three roommates in Napa, California, returned home after an evening together. By morning, two of them—Leslie Mazzara and Adriane Insogna—had been brutally murdered inside their home. Their third roommate survived, but investigators were left with a terrifying question: who entered the house that night, and why? In this episode of Unlawful Acts, Connie and Jocelyn examine the Napa Valley murders and the investigation that eventually led authorities to Eric Copple. With no obvious suspect and seemingly little explanation for the attack, investigators worked through physical evidence, interviews, and DNA while the case remained unsolved for months. The breakthrough would ultimately come from an unexpected connection to the victims and evidence that pointed directly toward Copple. What drove him to enter the home that night? How did investigators finally identify him? And what happened when the killer realized authorities were closing in? This is the story of Leslie Mazzara, Adriane Insogna, and the Napa Valley murders—a case that shattered a seemingly peaceful California community and revealed that the person responsible was closer than investigators initially knew.

For decades, the murders of four women in Northern California remained separated by time, geography, and unanswered questions. But investigators would eventually uncover a disturbing connection—and a suspect hiding in plain sight. In this episode of Unlawful Acts, Connie and Jocelyn examine the case of Joseph Naso, the convicted serial killer whose victims included Roxene Roggasch, Carmen Colon, Pamela Parsons, and Tracy Tafoya. Investigators noticed an eerie pattern: each victim's first and last names began with the same letter, earning Naso the nickname “The Alphabet Killer.” The investigation took an extraordinary turn when authorities searching Naso's home discovered photographs, handwritten writings, and a cryptic list containing references to women and locations. Prosecutors would use evidence accumulated over decades to build the case against him. How did investigators finally connect Naso to murders committed years apart? What did the writings and photographs discovered among his possessions reveal? And could the mysterious list point to additional crimes beyond the four murders for which he was convicted? This is the story of Joseph Naso and the Alphabet Killer case—a decades-long investigation involving cold cases, forensic evidence, disturbing records, and questions that remain long after his conviction.
