An inquiry has begun into why a driver was found dead by his family hours after the emergency services left the scene of a crash.
Chris Barclay, 19, from Kidsgrove, Staffordshire, was one of seven people in a car which hit a wall and rolled for 150m in Mow Cop on Friday night.
His family found his body in a field by the road at about 0400 BST on Saturday.
A post-mortem examination showed the Royal Marines Commando died instantly in the crash from severe head injuries.
Cause not known
Staffordshire Police have referred the investigation to the Independent Police Complaints Commission.
Mr Barclay had just recently passed out of commando training school.
A Staffordshire Police spokesman said the incident was thought to have happened at about 2300 BST on Friday.
His body was found approximately 30ft away from where his grey Vauxhall Nova came to rest.
The cause of the crash is not yet known.
The spokesman said the driver of the car was not in the vehicle when emergency services first arrived at the scene and could not be located despite a search of the immediate area.
After they left, Mr Barclay's relatives visited the scene at about 0400 BST and made the grim discovery.
Two of the six teenage passengers are due to be discharged from hospital on Sunday.
None of the six had life-threatening injuries, said police.
