9-year-old boy shoots and kills 13-year-old sister over video game, police say

A 13-year old girl in Mississippi is dead after being shot in the back of head Saturday by her 9-year old brother, after she refused to give up her video game controller.

Authorities in Monroe County responded to the scene, where they discovered that the boy had shot his sister.

The teenager was then rushed to Le Bonheur's Children's Hospital in Memphis, Tenn. and died late Sunday from her injuries.

It’s unclear as to how the boy got access to the firearm, with authorities saying that the children’s mother was in another room feeding lunch to other kids when the incident took place.

According to WLOV-TV, authorities will continue to investigate the circumstances of the shooting, with the Monroe County Sheriff saying, quote, “This is all new ground for us, we've never dealt with a kid shooting a kid at age 9. We don't know yet what kind of charges or if charges will be pressed. We want to make sure we’re doing everything correctly.”
