Forensic Files II S01E02 - On the Rocks

In December 1995, 17 year-old Krystal Beslanowitch leaves her motel room for a convenience store and doesn't return. That same day, her naked and bloody body is discovered near the Provo River with her head bashed in with nearby rocks. Blood evidence from the rocks would ultimately lead investigators to Krystal's killer, although it would take nearly 20 years and advances in DNA technologies to identify the murderer.
