PHOENIX -- Phoenix police say a man was fatally shot after using a Taser to stun an officer.
Police spokesman Tommy Thompson said 32-year-old Jefferson Duncan was shot multiple times after he tried to keep using the Taser.
Thompson said an 37-year-old officer was doing off-duty security near Interstate 17 and Cactus Road with another officer at an apartment complex when Duncan and 40-year-old Jonathan Parker showed "suspicious" behavior.
The two officers chased the two suspects and scuffled with Duncan before he grabbed one of the officer's Tasers and electrocuted the officer.
The officer said Duncan then aimed the Taser at his head and demanded his release.
The officer said he used his firearm on Duncan, who died at a hospital.
"As officers, that is the most vulnerable time that we have. So one can only imagine what could've occurred," Thompson said.
The 37-year-old officer was treated and released and is on administrative leave.
Police arrested Parker, who has an outstanding misdemeanor warrant.
