A 3-year-old girl shot and killed her 1-year-old sister in Tennessee, after a man placed the younger sibling in a bed with his gun.

Police say Robbin was shot Friday (9 November) morning at a Memphis apartment complex. Witnesses heard a gunshot and noticed the child had been hit.

While emergency services transported the child to the hospital, she was later pronounced dead.

Police say suspect Shawn Moore took the gun and fled the scene, but later turned himself in.

Memphis Police said they have charged Shawn Moore with criminally negligent homicide, being a convicted felon with a handgun and tampering with evidence in Robbin Keefer's death.

Shelby County Sheriff's Office records say the 25-year-old was booked into jail Friday night, Time.com reports.
