A nine-year-old boy shot dead his sister, 13, in the southern US state of Mississippi following an argument about a video game controller, local media reported on Monday.
The tragedy took place on Saturday when the girl refused to give up the controller, Monroe County Sheriff Cecil Cantrell said quoting reports. The boy then opened fire, striking his sister in the back of the head.The bullet pierced through the girl's brain, and she was taken to a hospital in Memphis, Tennessee, in critical condition. She died on Sunday.
An investigation was opened to determine how the young boy had access to a firearm and to what extent he was aware of the danger.
Such accidents are not rare in the United States, where the debate on gun control rages on.
