VIDEO: Phoenix Man Shot and Killed After Using Taser on Off Duty Officer

A Phoenix man was shot and killed Friday night after he used a stun gun on an off-duty police officer. Jefferson Duncan, 32, died at the hospital, said Sgt. Tommy Thompson, a Phoenix Police Department spokesman.

Two off-duty Phoenix police officers were working as uniformed security guards at an apartment complex, where they contacted Duncan for suspicious behavior. Duncan fled on foot and one of the officers chased him. Thompson said the officer caught Duncan and the men began fighting.

Duncan eventually gave up, Thompson said, and agreed to be taken into custody. But Duncan somehow got the officer's Taser from his belt and used it on the officer.

AZCentral is reporting that when the officer recovered, Duncan aimed the Taser at the officer's head and threatened to stun him again if the officer did not release him, Thompson said, adding that the officer pulled his firearm and shot "numerous rounds" at Duncan.
