A Sergeant with the Tennessee Highway Patrol was left to fight for his life after crashing on his motorcycle over the weekend.
Sergeant Allan Brenneis was on a ride in Dickson Saturday morning when the motorcycle in front of him had to stop short to avoid a previous crash.
Yet, Brenneis wasn't able to slow down in time. He was airlifted to the hospital in critical condition.
The driver and passenger of the other motorcycle, Roy and Jennifer Neiderwerfer, were also hurt.
The crash remained under investigation by THP.
