Authorities say the three officers involved in the death of unarmed Mexican man in Washington state fired 17 shots, including five or six that struck the former orchard worker.

Kennewick Police Sgt. Ken Lattin said at a news conference Wednesday that none of the bullets that struck Antonio Zambrano-Montes hit him in the back.

Lattin is a spokesman for the regional task force investigating the killing, which has led to protests and calls for a federal probe. Lattin says autopsy results are pending, and he couldn't be more specific about where the 35-year-old was shot.

Zambrano-Montes was killed Feb. 10 in Pasco, the gunfire captured on video by a witness.

Authorities say the Mexican immigrant was throwing rocks at officers, and a stun gun failed to subdue him. The Franklin County coroner has ordered an inquest into his death.
