A Tennessee police officer is in critical condition after his motorcycle collided with a state trooper’s vehicle while escorting Vice President JD Vance’s motorcade on Friday. The crash took place in Maryville, just outside Knoxville, around 6:11 p.m., according to local authorities.
The officer has been identified as Justin Brown of the Maryville Police Department. Police say he was providing security detail for the vice president when the collision happened. The Tennessee Highway Patrol confirmed that one of its marked SUVs was involved in the crash, but the cause is still under investigation.

Bystanders Rushed to Save Him
Witnesses nearby ran to help Brown immediately after the impact. Maryville Police Chief Tony Crisp said their actions likely saved his life. “We could never thank you enough. You are true heroes,” the chief said in a statement.
Brown was flown by helicopter to the University of Tennessee Medical Center in Knoxville. Hospital officials confirmed he underwent surgery and remains in critical condition. According to information shared by the department, Brown has begun to make small improvements and will likely remain hospitalized for a long recovery.
