A woman has died after a semi-tractor collided into her car, tipped over and lost its load Thursday.

According to the Stearns County Sheriff’s Office, 58-year-old Aaron Birr of Eden Valley was traveling northbound on County Road 2 in his semi-tractor hauling sand, when a car, driven by 90-year-old Marcella Cheeley of Cold Spring, was traveling westbound on Minnesota Street.

Cheeley made a left turn onto County Road 2 where she was struck in the driver’s side by the semi-tractor, forcing her car into the west side of the ditch.

Cheeley was pronounced dead at the scene. Birr was taken to the St. Cloud hospital.

The accident remains under investigation.
