(CNN) -- Authorities in Washington state found a body inside a fortified bunker where a man suspected of killing his wife and daughter was believed to be hiding, King County Sheriff's Office Sgt. Katie Larson said.
Deputies had been waiting out Peter Keller, who was believed to have been holed up inside the bunker near Seattle.
The body deputies found appeared to have suffered a self-inflicted gunshot wound, Larson said, but it was not immediately confirmed if it was Keller.
Deputies earlier said they had Keller, 41, contained inside the bunker.
Peter Keller Keller had not been seen since Sunday following a fire at his home, where the bodies of his wife and teenage daughter were discovered.
Authorities fired tear gas late Friday into the bunker, set into the Cascade foothills about 25 miles east of Seattle. It was unclear whether the gas went deep enough to have any effect.
