Ballistic evidence doesn't match Todd Kohlhepp's own confession, and Maria Awes visits the scene of the Superbike murders. She hears from one victim's family that alleges investigators missed the chance to question and apprehend Kohlhepp for the crime, something that could have prevented at least three additional murders. Awes investigates Kohlhepp's shocking life after the Superbike murders, starting his own real estate company, amassing an arsenal of high-powered guns, murdering one young couple and the boyfriend of a young woman he held captive in a shipping container, and allegedly killing others. She also learns intimate details from a former lover and investigates whether he had an accomplice.
