Updated at 1:50 p.m. ET: A plane crashed into a mountain in Washington state overnight, killing two men and a woman, authorities said Wednesday.
The single-engine Cessna 172 slammed into a wooded area on Little Si in North Bend, about 30 miles east of Seattle, King County sheriff's spokeswoman Cindi West told The Associated Press.
Susan Chapin of the sheriff's office told breakingnews.com that residents and officers in North Bend reported hearing the sound of a sputtering engine and an explosion that "woke everyone in the town up."
A helicopter crew spotted the wreckage using night-vision goggles. The bodies of three people were found inside the four-seat aircraft.
The identities of the victims were not immediately released.
The National Transportation Safety Board is investigating the cause of the crash.
Little Si, with an elevation of 1,576 feet, is a companion mountain named after its taller neighbor, 4,167-foot Mount Si.
