ALBERT LEA, Minn. (AP) - The sheriff investigating a fatal shooting at a state park in southern Minnesota says there's no evidence to support the gunman's claim of self-defense.

The man with the gun called 911 Tuesday night to report the incident at Myre-Big Island State Park near Albert Lea. He told authorities the man he shot had come after him with a baseball bat.

Freeborn County Sheriff Kurt Freitag says the victim was sitting in his car when he was shot and the gunman was outside and fired through the vehicle's closed window. Freitag says the car was in reverse and the victim had his foot on the brake.

Charges against the gunman could be filed Thursday.
