Authorities say a 14-year-old boy who was handling a loaded shotgun apparently accidentally shot and killed his 13-year-old sister.
The Clinton County sheriff's department says it responded Saturday afternoon in Ovid Township, where they found the girl already dead.
WLNS-TV reports the boy has been released back into the custody of his parents.
An autopsy was planned and investigators were awaiting the results.
Sheriff Wayne Kangas says it appears to be "just a tragedy."
Grief counselors with the Ovid-Elsie Area Schools are being made available for students on Monday.
