Incident

Trooper Mark Phebus was shot and killed on FM 1774 near Magnolia, Montgomery County, when he stopped a husband and wife who were bumping each other's cars in a domestic dispute. Trooper Phebus was off duty and returning home after a weekend out of town when he encountered what he believed to be a vehicle crash after seeing the vehicles collide. He identified himself and asked the female to find a phone to call 911. The male subject shot Trooper Phebus after she left the scene. A capital murder warrant was issued for the male subject but he committed suicide before being arrested. Trooper Phebus had served with the Texas Highway Patrol for seven months.

I served 1985 to 1993. You served too, before the badge - different uniform, same idea. You go where you are sent and you do not get to pick the call.
