A Phoenix man died of his injuries after he was shot by another man during an argument Sunday morning involving his ex-wife, authorities said.

Phoenix police identified the dead man as Brandon Branch, 34.

Shortly before 10 a.m., officers found Branch wounded near 37th Avenue and Camelback Road, said Sgt. Jonathan Howard, a Phoenix police spokesman.

He was transported to a nearby hospital in critical condition, Howard said said.

Witnesses described a vehicle involved in the confrontation, which was found in the 4300 block of West Clarendon Ave., Howard said.

A preliminary investigation showed Branch had been in an ongoing dispute with his ex-wife, Howard said. His ex-wife and a friend went to search for Branch to confront him. The ex-wife was talking with Branch when he produced a handgun and threatened to kill her, Howard said. The friend, who had remained in the car, responded by producing his own handgun.

The two men exchanged gunfire, with Branch the only man struck, Howard said.

The ex-wife's friend has been cooperating with investigators, Howard said.
