WEST PALM BEACH, Fla.  - Authorities say two deputies allegedly wrestled with an impaired motorist in South Florida and used stun guns before one of them fatally shot the man.

Authorities on Friday said 44-year-old Richard Montero was pronounced dead after he was taken to a hospital.

Two deputies on patrol spotted a vehicle that was apparently broken down. Authorities saw Montero was impaired and decided to call his girlfriend to come get him instead of arresting him. Authorities say when he learned his car was going to be towed he became violent. They said he and the deputies got into a scuffle. He was struck twice with stun guns, but with little effect.

Authorities say the deputies feared he would get one of their guns and one of them fired at least two shots.
