KANSAS CITY, Mo. (AP) – Kansas City police have disclosed the death of a 4-year-old girl who was shot in the head earlier this month by a 6-year-old boy.

Police said Tuesday that preschooler Trinity Ross was taken off life support last week, seven days after the accidental shooting.

The Kansas City Star reports an adult had briefly left the preschooler and two boys, ages 5 and 6, alone in the living room of Trinity’s home when the older boy found a gun on a chair. The adult heard a gunshot and found Trinity on the floor with a wound in her forehead.

Police said the older boy apparently found the five-shot revolver under a jacket. The adult said it belonged to a relative of the boys.

No charges have been filed.
