(AP) — An autopsy report shows the 13-year-old boy who was killed by a Northern California sheriff’s deputy while holding a pellet gun was shot seven times.

The preliminary report from the Sonoma County coroner’s office says the two fatal wounds hit Andy Lopez in his right hip and the right side of his chest.

Investigators believe the deputies who encountered the boy Tuesday afternoon fired eight rounds. The timeline released by Santa Rosa police says those shots were fired within 10 seconds of the deputies’ first report of a suspicious person.

The deputies say the teen was carrying what looked like an assault rifle and had his back toward them at first. They ordered him to drop the weapon, but instead he turned toward them.

Only after the shooting did they realize that he was carrying a pellet gun that looked like an AK-47.
