An Irmo woman has died in a single-vehicle crash.

The Highway Patrol says it happened Thursday morning in the 1700 block of Burning Tree Road, near the I-26 exit to St. Andrews Road.

Troopers say the car veered off the road and struck a tree.

Lexington County Coroner Harry Harman says the driver, 22-year-old Ashley Mitchell, died at the scene.

A 4-year-old boy who was a passenger was treated for non-life-threatening injuries.
