RCMP are investigating a rollover in Grande Prairie early Saturday morning that left one man dead.

Mounties and EMS rushed to the scene at around 12:20am near Pinnacle Drive and 116th Street in the city and found the 31-year-old man dead.

Investigators believe the man's GMC Sierra was driving southbound when he is thought to have lost control. RCMP say he then rolled, crashed through a fence and came to a stop on the trucks wheels.

The man's name has not yet been released and RCMP are still trying to determine whether drugs or alcohol played a factor in this crash. (twd)
