City police and the Sonoma County district attorney’s office are also investigating.

The Santa Rosa Police Department said two sheriff’s deputies encountered the boy around 3:15 p.m. on Tuesday. Witnesses say that at least one of the deputies yelled “drop the gun” twice.

Ten seconds after their initial report, one of the officers called in that “shots have been fired.”

Sixteen seconds later, the deputies called for medical help. The boy was pronounced dead at the scene. The Sonoma County coroner said he found seven “apparent entry wounds.”
