RICHMOND, Va. - A teenage boy in Richmond, Va. is accused of assaulting a 12-year-old girl and killing her 8-year-old brother when he tried to intervene and protect her.
Officials on Friday identified the deceased boy as 8-year-old Martin Cobb.
Richmond police spokeswoman Dionne Waugh said the teenage assailant has been detained and was being medically evaluated Friday.
Waugh said police plan to charge him in the attacks, which reportedly took place Thursday afternoon.
Neighbors told the Richmond Times-Dispatch that the boy died trying to protect his sister from the attacker. Neighbor Sudan Aunu said the girl is alive today because of her brother.
