Buried Secrets: Cold Cases Uncovered (2006)

This fascinating NBC News production looks into the gripping world of "cold cases," long-ago crimes solved when some new evidence comes to light. This program follows two brutal murder cases in which the dedication of the victim's loved ones, police, and prosecutors finally led to some kind of closure. "Silence in a Small Town" looks at the 1980s disappearance of a shy high school student and the measures that detectives ultimately took to expose the truth; and "Hunting the Unicorn" examines the case of infamous "hippie ax-murderer" Ira "the Unicorn" Einhorn, who spent a quarter of the century on the run, leading authorities on a cunning and intricate chase through Europe.
