Authorities believe a 30-year-old woman fatally shot two boys ages 5 and 8 before killing herself.

State police said in a news release Sunday that an initial investigation indicates the woman killed the boys Saturday, but they declined to release additional details.

Authorities arrived at the scene, about 160 miles south of Pittsburgh, and found the bodies of the woman, who also had been shot, and the older boy.

The 5-year-old was still alive when authorities arrived and died shortly after, state police said.

It was not immediately known how the three were related.
