Police are investigating a fatal single vehicle collision on old Richmond Road south of Fallowfield. 

Paramedics say a 57-year old man was pronounced dead at the scene after his pickup truck slammed into a tree just after 8 p.m. Tuesday, Aug. 5, 2014.  He was the lone occupant of the vehicle. 

Police say it's too early to tell whether speed or alcohol may have been factors in the crash. 

A stretch of Old Richmond Road was shut down from Fallowfield to Rushmore while collision investigators combed the scene.
