A Washington state police officer says a man was holding a large rock and drew back his arm as if he was going to throw it when the officer and others opened fire and killed him.

A recording of Officer Adam Wright describing the shooting of Antonio Zambrano-Montes, a Mexican national, was released Wednesday by authorities in Franklin County.

The killing of 35-year-old Zambrano-Montes was captured on video and sparked weeks of protests in the central Washington city of Pasco.

A prosecutor is deciding whether the three officers who shot Zambrano-Montes should face criminal charges.

Wright says he feared officers would be injured or killed by the rock.

The recording was among 10 released by the Franklin County prosecutor. Other documents and recordings were released last week.
