A sheriff's deputy was shot and killed Saturday after responding to reports of gunfire at a trailer park in western Ohio, the sheriff said.
A second law enforcement officer also was shot at the Enon Beach trailer park in suburban Springfield.

The unidentified suspect was shot and killed, said Kelly.

"Our deputy never had the opportunity to return fire or take cover," said Kelly.
She had responded to reports of shots in the area and had begun her initial investigation when she was killed,
