Forensic Files II S01E12 - Killer Snapshot

In November 2009, a young woman's body is found in Moss Bluff, Louisiana. Tattoos on the victim help to identify her as 19 year-old Sierra Bouzigard, and while the crime initially appears to be sexually motivated, no DNA is recovered from Sierra's rape kit. However, DNA under Sierra's fingernails matches DNA evidence found on a candy wrapper near the scene. After several years with no answers, Blake Russell is identified as a suspect using new DNA technology.
