(CNN) -- Searchers in Washington state have found the wreckage of an airplane that went missing with 10 people on board, a Yakima County Sheriff's representative said.
A plane similar to the one pictured went missing Sunday. It was carrying nine skydivers and a pilot.
The plane was found south of Mount Rainier; it had been carrying nine skydivers and a pilot.
No signs of life were found, and the bodies of at least seven of those on board were located, said Yakima Valley Emergency Management spokeswoman Lisa Truhlicka.
The wreckage was found in an area with steep terrain, among heavy timber and brush, just 200 yards from where the last radar signal from the plane was detected, Deputy Dan Cypher said.
The rough conditions and darkness have so far prevented a full search of the wreckage, he said.

"Rescue teams are bivouacking at the site," he said. "At daybreak we will do a more thorough search."
The wreckage was in the immediate area of the search focus, Cypher said.
"The teams did smell fuel and followed the odor and came across the wreckage," he said.
The plane, a single-engine a Cessna 208 Caravan, fell off radar at 8 p.m. (11 p.m. ET) Sunday, about a half hour after taking off from Boise, Idaho, bound for Shelton, Washington, according to the FAA.
Ground and air rescue teams had been searching rugged terrain in Washington state.
Weather conditions were good for the flight, officials said.
A camper reported seeing a low-flying plane Sunday evening and then hearing a crash, Nisha Marvel of the Washington State Department of Transportation told CNN.
WSDOT's Aviation Division was coordinating the air search, and the Yakima County Sheriff's Department was handling the ground search. The air search, which began early Monday, included two volunteer planes and two helicopters, Marvel said. About 50 people took part in the search.
The search area was southwest of Rimrock Lake, which is south of Mount Rainier in Washington state, Yakima County Search and Rescue said.
The plane was equipped with an emergency locator transmitter, according to Geoff Farrington, of the family-owned Kapowsin Air Sports, which owns the missing plane. But no emergency signal had been detected as of Monday evening, according to WSDOT.
The nine skydivers aboard the plane regularly participated in jumps with Skydive Snohomish in Snohomish, Washington, said Elaine Harvey, a spokeswoman for the company.
She said the group had flown into Boise for a skydiving event about 15 miles away in Star, Idaho.
"We are a very close-knit community," she said. "This is devastating." E-mail to a friend
