The body of a man was found in a car wreck more than six hours after emergency crews were called to the Keysbrook crash on Saturday.
A nearby resident called police about 7.30am after coming across a Nissan Patrol that had crashed into a tree and ended up on its roof on the South West Highway near Boyd Street.
The West Australian understands the initial report to police suggested the car had been abandoned. One woman, who declined to be named, said she got on her hands and knees to inspect the wreckage but could not see into the back of the vehicle because a piece of carpet and a big tree had "skewered" the vehicle.
Police did not find the body. A volunteer firefighter crew called about 11am to clean up a fuel spill did not either.
The West Australian understands a man who was looking through the wreckage later saw the body and called police.
Neighbours in the semirural area said emergency crews returned to the scene, including firefighters to help remove the victim from the wreckage. He was identified as a 30-year-old man from Esperance but his name was not released.
Major crash squad officers said they believed the crash occurred between 2am and 7.30am on Saturday.
They believe another two people were in the vehicle at the time of the crash and have identified them but were still searching for the pair yesterday afternoon. The car had not been reported stolen.
Skid marks were clearly visible on the bitumen from the north-bound lanes of the highway towards the tree that was struck by the Nissan.
A statue of an angel engraved with the words "Bless this Garden" had been left at the scene.
Police have urged the two survivors of the crash to come forward, or anyone else with information
on the crash to contact Crime Stoppers on 1800 333 000.
