PHOENIX — A 12-year-old boy was hospitalized with life-threatening injuries Sunday after his uncle showed him his handgun and it accidentally went off, according to police.

Robert Chavez was arrested and charged with aggravated assault and misconduct after showing his nephew his gun, said Sgt. Jonathan Howard, a Phoenix police spokesman.

According to court documents, Chavez told officers he thought the gun was unloaded before pulling the trigger. The bullet hit his nephew in the chest.

Chavez is prohibited from possessing a firearm, Howard said.

He admitted to officers that he bought the gun a week ago even though he knew he was not allowed to have one, according to court documents.

At last check, the boy's condition was improving, Howard said.

Chavez's bond was set at $50,000. His next court appearance was scheduled for Feb. 29.
