Police say a 19-year-old Long Island, New York man has been arrested in the fatal stabbing of his younger brother.

Suffolk County police responded to a 911 call at around 7 p.m. Friday in Bay Shore. They found 17-year-old Brian Castillo with a stab wound to the neck. He was pronounced dead at the scene.

The victim’s brother, Robert Rivera, was arrested on a charge of second-degree murder.

Newsday reports the brothers were playing a video game when he was stabbed. 

Assistant Suffolk County District attorney Lawrence Opisso told the newspaper the victim went to his front yard and told his father “look what Robert did to me.” 

It’s not clear if Rivera has an attorney who can speak for him.
