A Virginia state trooper was shot and killed on Thursday afternoon at a Greyhound bus station in Richmond, Virginia.
Trooper Chad Dermyer, 37, was at the bus station for a training exercise to locate suspicious people.
Dermyer engaged in a conversation with the man just inside the entrance when the man opened fire at around 2:45 p.m.
Dermyer was transported to the hospital but died from his injuries.
The gunman, who has not been identified was shot by other troopers. He was taken to VCU medical center where he died from his injuries as well.
Police have not identified a possible motive for the attack.
Two women inside the bus station were shot as well but neither sustained life-threatening injuries.
Greyhound closed the bus station for the rest of the day on Thursday and has not said if they plan to re-open on Friday.
Dermyer had just been transferred to a counter-terrorism unit. About a dozen members of that unit were at the bus station for the training exercise.
Dermyer joined the Virginia State Police Department in 2014. He previously served in the U. S. Marine Corp.
