A northwest Arkansas man shot himself to death after a Lowell police officer pulled him over to investigate a domestic disturbance, police said.

Lowell Police Chief Joe Landers said that 36-year-old Richie Woods got into a fight with his estranged wife at a home outside of Lowell on Sunday. Woods left the home, and Lowell police were asked to locate him.

Sgt. Robert Jones pulled Woods over in a parking lot, and Woods shot himself in the head while sitting in his vehicle, police said. He was declared dead at the scene.

Jones, who is on administrative leave, did not pull his gun until after he heard the shot, according to police.
