Missouri State Highway Patrol Trooper Juston Wheetley says Christopher Parsons was shot and killed while responding to an emergency call early Saturday about an unconscious person near Mineral Point, a community of about 350 residents southwest of St. Louis. Parsons was shot as emergency crews loaded the unconscious person into an ambulance.
Wheetley says the suspect, 30-year-old Gary Sancegrow of Mineral Point, was taken into custody without incident at about 5:15 p.m.
Several law enforcement agencies including the FBI had been searching for Sancegrow, who Wheetley says fled the scene on foot.
Wheetley says associates of Sancegrow brought him to a law enforcement checkpoint that had been set up in Mineral Point.
