'Chilling' video diary shows man's plan to kill family

(CNN) -- A video diary released Thursday gives an eerie view into the planning process of a man police say murdered his wife and daughter and then killed himself in a bunker he built in the woods in Washington state. Peter Keller, 41, shot and killed his wife, Lynnettee Keller, and their 18-year-old daughter, Kaylene Keller, and then set a fire in their Seattle-area home in April, the King County Sheriff's Office said. A video diary Keller left behind touched on his decision to kill his family but still gave little information about his reasons. "A while ago I used to sit here and think, you know, this whole thing is crazy," Keller said as he wandered in the woods wearing a gray sweatshirt, his hair disheveled. "The more I thought about it. The more I understand it. I don't really feel bad about it. It is just the way it is. ... I won't have to worry about Lynnettee or Kaylene. Everything will just be taken care of. It will just be me." Washington slaying suspect believed hiding in bunker King County Sheriff Steve Strachan said the video, and other evidence found at the fire-damaged home and in the bunker, revealed that Keller was planning the construction of the bunker as far back as 2004.
