NORTH BEND, Wash. (AP) -- Washington state authorities are maintaining a tight watch on an elaborate, underground bunker that might be hiding an armed survivalist suspected of killing his wife and daughter.
Authorities pumped tear gas into the structure yesterday and report hearing movement inside. But the dozens of officers are maintaining a perimeter because they believe the man inside is heavily armed and that bunker in a wooded area might be booby trapped.
Sheriff's officials say they're not sure the gas penetrated deep enough to reach the person inside, who they believed is 41-year-old Peter Keller. They also believe he has a gas mask.
Keller has not been seen since a fire at his North Bend-area home Sunday led responders to discover the bodies of his wife and daughter. The two had been shot to death.
