GRAND BLANC (WJRT) (8/28/2018) - Investigators believe a medical issue led to a deadly crash that claimed the life of a contracted maintenance supervisor for Grand Blanc Community Schools.
The crash was discovered around 6 a.m. Tuesday on Jewett Trail along the south end of the Grand Blanc High School property. Administrators said a vehicle crashed into a fence and the corner of a brick maintenance building.
Cheryl Rayner, a custodial site supervisor for Knight Facilities Management, was taken to an area hospital where she was pronounced dead later Tuesday.
Rayner had worked in Grand Blanc schools since 2004. She was alone in her vehicle, which was the only one involved in the crash.
Investigators believe she suffered a medical issue that caused her to drive out of control.
No students were in the area because classes don't begin for Grand Blanc schools until Sept. 4.
