As her kidnappers threatened her life, Elisa Levy found hope through memories of her family, as seen in a recent episode of Dateline: Secrets Uncovered.

Rhoni Reuter was just weeks away from giving birth to a daughter when she was gunned down in her condo on October 4, 2007. 

"I put my family first," Josh Powell insisted in a final eerie interview with Dateline: Secrets Uncovered before investigators say he killed his two young sons during a court-ordered visitation.

Before disappearing, John and Linda Sohus had lived on the same property as a mysterious tenant calling himself Christopher Chichester — but after the couple vanished in 1985, detectives would learn Chichester was not the man he claimed to be.
