The Missouri Highway Patrol is trying to locate a tractor-trailer rig after a brake shoe that fell from the truck hit a Butler woman in the head, critically injuring her.

The incident that took place about 4 p.m. Friday on Missouri 52 just west of U.S. 71 resulted in Dianna L. Cumpton, 52, being flown to a Kansas City hospital in critical condition.

As the patrol described the accident, Cumpton was injured when a steering brake shoe fell from the tractor unit, flew into the windshield of Cumpton’s truck and then hit Cumpton in the head.

The patrol is trying to locate people who might have been asked to do brake work on the truck in an effort to locate the driver.

People with information can contact Patrol Troop A at (816) 622-0800.

I have personally seen this happen before, brake drum flew apart and took out my radiator one time many years ago. If it would have been about 6″ taller it would have went clear through the cab of my truck..
