DETROIT (AP) — A gunman who opened fire with a shotgun during a church service Sunday morning killed a woman and wounded two people before he left and shot himself a mile from the church, police said.

Investigators believe a domestic dispute led to the shooting at Zion Hope Missionary Baptist Church about 11 a.m., said Second Deputy Police Chief James Tate.

A 9-year-old child, sitting near the unidentified woman who died, was hit in the hand by a buckshot pellet, Tate said. Police didn't know the relationship of the pair.

As the gunman fled the church, he critically shot a man who was trying to protect his wife from a carjacking attempt, officials said.

Many of the hundreds of people in the church screamed as they ducked under the pews for protection, said Ann Armstrong, 30, who was attending the service.
