A 12-year-old shot and killed a man after he broke into the boy’s home and shot his grandmother.

Police said 73-year-old Linda Ellis’s home in Goldsboro, North Carolina, was broken into Saturday night by two masked robbers, and after one of the intruders shot her in the leg, her grandson opened fire, killing one of the men, according to WRAL.

“[The intruder] just shot his grandma. … He would have shot him, too. He would’ve shot me, too. He would’ve killed us all,” said Randolph Bunn, the boy’s great-uncle.
