Stolen Voices, Buried Secrets - Season 1 Episode 4 Cold As Ice

On a warm California evening in the summer of 1991, 23 year-old grad-student and music-lover Denise Huber attends a concert. But when she fails to return home and her car is found abandoned on the freeway, Denise's parents begin to fear the worst. Despite a wide spread search, Denise remains a missing person for three long years. But her parents refuse to give up hope that one day she'll return home. Then in 1994, an Arizona couple reports a mysterious moving van parked in a stranger's yard. When the Arizona police investigate, what they discover is both chilling and heartbreaking.
