(AP) — A man died in a grain bin accident in the small south-central Nebraska city of Edgar.

The man died Tuesday morning in a grain bin on the north edge of the Clay County city.

Edgar Fire Chief Gene Babcock says it’s unclear what happened, but the man was scooping corn out of his bin when he somehow got trapped inside. He died before crews could pull him out.

Babcock declined to name the man who died.

Fire crews and volunteers were at the bin for nearly 90 minutes, working to move out corn and free the man.
