On Tuesday afternoon, two Sonoma County deputies spotted the boy carrying what they thought was a semiautomatic weapon, according to the Santa Rosa County Sheriff's office. They pulled over and yelled at the teen to put his weapon down, according to reports.
A statement from the Sheriff's office described what happened next:
"One of the deputies described that as the subject was turning toward him the barrel of the assault rifle was rising up and turning in his direction. The deputy feared for his safety, the safety of his partner, and the safety of the community members in the area."
According to California authorities, the deputies fired multiple rounds and hit Lopez several times. They then handcuffed the unresponsive boy and called for an ambulance after administering first aid.
They found the fake rifle on the ground, as well as a plastic hand gun tucked in the boy's waistband.
Lopez was pronounced dead at the scene.
