Two Sonoma County deputies saw the boy walking with the replica weapon around 3 p.m. Tuesday in Santa Rosa. Lt. Dennis O'Leary says they repeatedly ordered him to drop what appeared to be a rifle before firing several rounds.
The boy fell to the ground. Deputies handcuffed him and began administering first aid, but he was pronounced dead at the scene. O'Leary says deputies also found a plastic handgun in his waistband.
The boy's father, Rodrigo Lopez, told the Press Democrat of Santa Rosa the victim was his 13-year-old son, Andy.
The deputies have not been identified.
