This image from video provided by the King County Sheriff's Office Thursday July 12, 2012 shows Peter Keller recording a video explaining why he killed his wife and daughter and retreated to a remote bunker in Washington's Cascade Mountains. He was bored. Keller shot his wife, Lynnettee, and his 18-year-old daughter, Kaylene, at their home in North Bend, east of Seattle, in April.  (AP Photo/King County Sheriff's Office)
