A 13-year-old boy fatally stabbed his brother with a steak knife after the 16-year-old refused to turn over a video game controller, authorities said.

Jahmir Ricks was charged with first-degree murder in the death of Antwan Ricks at their home outside Philadelphia. The older boy died of a single stab wound to the chest, police said, and a bent and bloody knife was recovered from the home.

Lansdowne police said the younger boy told them, "I just stabbed my brother," when they arrived at the home Sunday.

Police believe the argument started when Antwan Ricks would not turn over the game controller after losing a game to his brother. Police Chief Daniel Kortan said the rules of the house were that the person who lost had to give someone else a chance to play.

The argument escalated into a brawl, and the younger boy grabbed the knife, Kortan said.

Antwan Ricks was pronounced dead at a hospital.

Jahmir Ricks, who was charged as an adult, was being held without bail. It was not immediately known if he had obtained an attorney. He faces charges of third-degree murder, assault, recklessly endangering another person and possession of instruments of crime.
