‘We’re Ready for Battle’: Sheriff Joe Arpaio Arms Officers With AR-15-Style Rifles After Comrade Was Killed in Driveway (+video)

PHOENIX (TheBlaze/AP) — A detention officer with the Maricopa County Sheriff’s Office died Thursday after being shot in the driveway of his Arizona home while he prepared to head to work. Now, all officers in the department are being armed with rifles by the direction of Sheriff Joe Arpaio for added protection.

Jorge Vargas, 27, was rushed to a hospital after the 4 a.m. attack and died a short time later, Phoenix police Sgt. Trent Crump said.

No one was in custody yet and there was no information on a motive.

“It’s really a whodunit,” Crump said, adding that investigators are looking into whether the shooting was connected to the victim’s job.

“Anytime we have a homicide and the suspect is unknown, we start with our victim,” Crump said. “But we can’t rule out a random act.”
