Forensic Files - Season 7_ Episode 17 - Chief Evidence - Full Episode

"In 1996, a suburban Seattle couple was found murdered in their home. Investigators initially believed it was a drug deal gone wrong, but no drugs were found at the scene, and the victims' blood wasn't on the suspects' clothes. The key to the case came from an unlikely source: the couple's dog, Chief."DNA evidence from Chief, a Chow-Chow mix, linked one of the killers to the scene in one of the first cases where dog DNA was used to secure a conviction. Kenneth Leuluaialii and George Tuilefano were both sentenced to life in prison without parole.
