A 4-year-old boy was fatally shot Thursday in what police said was a tragic, avoidable accident. The shooter was the boy's 4-year-old female cousin.

Sgt. Michael Woody, a Detroit police spokesman, said the children were playing in the back bedroom of a home when the girl found a rifle — loaded and not locked in a case — underneath the bed. He said the girl pointed the gun at her cousin and pulled the trigger, shooting him in the chest. Woody said police were called to the home at about 4:50 p.m. He said the child was taken to Henry Ford Hospital, where he was pronounced dead on arrival.

Police said there was one adult, the grandfather, in the home at the time of the shooting.
