A 5-year-old Kentucky boy who received a .22-caliber rifle as a gift accidentally shot and killed his 2-year-old sister on Tuesday, according to state police.

The toddler was shot at just after 1 p.m. local time on Lawson’s Bottom Road in Cumberland County, police said. The girl was taken to Cumberland County Hospital and later pronounced dead.

The mother of the two children was at home at the time of the shooting, Cumberland County Coroner Gary White told the local newspaper, the Lexington Herald-Leader. He said that the family did not realize that there was a shell inside the gun. The firearm was kept in a corner, he said.

“It’s a Crickett,” Cumberland County Coroner Gary White told the paper. “It’s a little rifle for a kid.”

“The little boy’s used to shooting the little gun,” White said.

The shooting occurred while the boy was playing with the rifle, police said. It was “just one of those crazy accidents,” White told the Herald-Leader.
