SEATTLE (AP) -- Searchers found another body in the debris from a massive landslide in Washington state, bringing the death toll to at least four.
Snohomish County Fire District 21 Chief Travis Hots said Sunday that crews were able to get out to the debris and found one body buried in the mud. At least 18 people remain missing.
Hots said emergency responders and technical rescue personnel found "no signs of life" as they scoured the area.
The 1-square-mile mudslide that hit Saturday morning also critically injured several people and destroyed about 30 homes.
The slide occurred about 55 miles north of Seattle.
Authorities say 18 people are unaccounted for after a massive mudslide in Washington state killed at least three people and forced evacuations because of fears of flooding.
Snohomish County Fire District 21 Chief Travis Hots said at a news briefing Sunday that they suspect there are people out there, but the situation is too dangerous for rescuers.
He said the slide is "basically like quicksand." Searchers had to turn back late Saturday after attempting a rescue in an area where signs of life were heard.
Authorities are using helicopters, and plan to drop rescuers into areas if they find signs of life
The slide has blocked about a mile of a state highway. Several people -- including an infant -- were critically injured and at least six houses were destroyed.
Rescue crews continued searching for survivors late Saturday night after voices were heard in the debris field of a massive landslide that killed three in rural Washington state.
Snohomish County Fire District 21 Chief Travis Hots said at a news briefing late Saturday that people were "yelling for our help" and rescuers would work through the night.
Hots said it wasn't clear how many people might still be alive.
The massive landslide of mud, trees and rocks happened about 11 a.m. Saturday morning. Several people - including an infant - were also critically injured and at least six houses were destroyed.
A third person has died following a massive landslide in rural Washington state that injured at least eight others and destroyed six houses, Snohomish County authorities said.
The slide of dirt, trees, rocks and other debris that was at least 135 feet wide and 180 feet deep hit just before 11 a.m. Saturday.
The Snohomish County sheriff's office initially reported that two people had been killed. Authorities said later Saturday that one of the people rescued died at a hospital.
The landslide completely blocked State Route 530 near the town of Oso, about 55 miles north of Seattle.
