The police dispatch on the radio Friday night was a staccato of static, terse orders, and alarm. An officer was down. A suspect was “out,” presumably on the ground, awaiting EMS. There was a search for another possible weapon.

The boy, who has not been named, was charged with murder, attempted murder and possessing illegal weapons. The officer who died early Saturday morning was identified as Detective Joseph Azcona.
