SUMMIT COUNTY, Colo. — A man accused of intentionally crashing his vehicle into a Summit County bus in May is now facing charges of attempted murder and assault.

That man is Joshua Stephen Pierce, 32. He has disputed the charges, saying his on-again, off-again girlfriend, who was also in the vehicle, was trying to commit suicide, took the wheel and caused the crash in an effort to do so. 

Authorities say they have video evidence that proves otherwise.

According to the Summit Daily News, police say a video taken inside the bus shows Pierce in full control of the steering wheel with his arms braced for impact while directing his Subaru from a westbound lane on Highway 6 into the front of a bus in an eastbound left turn lane.

Following the crash, police also said Pierce told officers at the Summit Medical Center that he purposefully drove his car into the bus during an argument with his girlfriend, who was airlifted to the medical center with several broken bones, internal damage and a torn aorta.

A 3-year-old and a 15-year-old aboard the bus also suffered minor injuries.

Pierce is being charged with second-degree murder, endangering public transportation, vehicular assault and four counts of third-degree assault. All but the basic assault charges are felonies, and Pierce could face between four and 32 years if convicted.

He is set to make a court appearance on Jan. 2.
