Hunt for a Survivalist, Peter Keller, Ends With Body Found Authorities in Washington State blew open a survivalist bunker on Saturday to find what they believe to be the body of a man suspected of killing his wife and daughter - the culmination of a lengthy manhunt that drove officers into the sludge-packed foothills of the Cascade Mountains. Since Friday afternoon, SWAT officers in King County had surrounded the elaborate, underground structure where they believed the man, Peter Keller, 41, had gone into hiding. Mr. Keller is suspected of killing his wife and 18-year-old daughter, then setting his house ablaze last weekend and retreating into a bunker he began constructing in 2004, the authorities said. Around 10 a.m. on Saturday, officers found a body inside with an apparently self-inflicted gunshot wound. "We believe it to be Keller," Sgt. Katie Larson of the King County Sheriff's Office said in a telephone interview. On April 22, Sergeant Larson said, a fire at Mr. Keller's home in North Bend, Wash., east of Seattle, led responders to the bodies of his wife and daughter, who had both been shot to death. Mr. Keller tried to burn the house down, but was unsuccessful, Sergeant Larson said, allowing authorities to recover a hard drive with photographs inside the home. They discovered one grainy image that appeared to have come from the bunker, which authorities believe Mr. Keller had been working on for eight years, Sergeant Larson said. A detective enhanced the photograph, Sergeant Larson said, then used triangulation to estimate where the bunker might be situated. Interviews with people who said they had seen Mr. Keller's pickup truck parked near the head of the trail, at Rattlesnake Ridge, also helped lead authorities to the correct location, Sergeant Larson said. But officers, fearing that Mr. Keller was armed and that the bunker could be outfitted with traps, did not enter right away. Authorities traded shifts over nearly a full day, sloshing across the slick, steep terrain outside the bunker.
