Family murderer Peter Keller recorded a chilling video diary about two weeks before murdering his wife and daughter in their North Bend, Wash., home in April.

The King County Sheriff's Office has released a nearly 10-minute video of clips self-recorded by Keller, 41, in the woods where he built his escape bunker over the course of eight years, according to police. After the murders, Keller killed himself in the bunker during a SWAT stand-off.
