OKTAHA, Oklahoma - The Oklahoma Highway Patrol is still trying to determine why a Oktaha man crashed his car into a Union Pacific train which had stopped at a railroad crossing in Muskogee County Wednesday evening.

Troopers say the impact killed the driver, 49-year-old Christopher Harris of Oktaha. 

The OHP report states Harris was headed west on 123rd Street South when his 2017 Jaguar struck the northbound train just before 9 p.m.
