The King County Sheriff’s Office Friday located the bunker on Rattlesnake Mountain near North Bend that Peter A. Keller, charged in the murder of his wife and daughter, was believed hiding in.

The bunker is on a hillside near the Rattlesnake Ridge Trail off Interstate 90. SWAT teams with the Sheriff’s Office and the Seattle Police Department had been searching the area since Friday morning.

Keller was charged with two counts of first-degree murder and one count first-degree arson after his wife Lynnettee and daughter Kaylene were found dead April 22 at a home in the 4700 block of Southeast 159th Street in North Bend.

A neighbor had called 911 to report smoking coming from the roof of the house. Firefighters had to force their way through the front door, which was barricaded by a couch and other furniture, according to the Sheriff’s Office.

Sheriff’s detectives have been unable to find the 41-year-old Keller, who is 5-foot-5 and weighs 175 pounds.

Based on the photos detectives discovered of the bunker at the crime scene, Keller had been building for it for at least eight years. The bunker appears to be fortified by logs, dirt and was well hidden, according to the Sheriff’s Office.
