On a freezing November night in 2015, 30-year-old nursing student Angila Wilder was stabbed 44 times inside her home in Minot, North Dakota. The brutal attack happened while her two-year-old son slept safely in the very next room. When her fiancé, Christopher Jackson, discovered the scene after returning from an overnight shift, investigators immediately began untangling a web of jealousy, obsession, and domestic violence.

The evidence quickly pointed toward Angila's ex-husband, Ritchie Wilder Jr., and his new wife, Cynthia. What started as a bitter custody dispute had morphed into a calculated, years-long plot to eliminate Angila entirely. The case features one of the most chilling interrogations in true crime history, a failed prison escape, and a stunning undercover recording that finally brought the whole diabolical plan crashing down.

On June 19, 1982, James and Virginia Campbell were shot to death in their Houston home while they slept. The shocking answer to who killed them: their own daughter Cindy and her boyfriend David West. Cindy stood to inherit money and was willing to murder her parents to get it—while her young children slept down the hall. This case features one of the most incredible undercover investigations in true crime history, as a 23-year-old private investigator befriended David West for months to extract a confession. A chilling story of greed, betrayal, and family murder.
