A Stearns County high school football coach under investigation by a school district and the sheriff’s office has stepped down.

A lawyer for the Kimball Area School District said Johnny Benson resigned the same day a special school board meeting was held to discuss the matter.

Benson left the district on Oct. 30, while the district says they were conducting an investigation into a complaint made against him and were cooperating with a criminal investigation.

A search warrant filed in October with the court stated law enforcement were investigating allegations of a possible sexual assault involving the now former head football coach and a player earlier in October.

The warrant says authorities were called to St. Cloud Hospital Oct. 10 to investigate a “possible sexual assault” after a player’s family felt he “wasn’t himself.”

The warrant alleged the player recalls being treated by the coach for a lower back injury in the locker room after practice.

But the warrant goes on to say the player doesn’t remember if he “had fallen asleep or what had happened” for the next three hours when his mother found him alone in the locker room.

While the school district investigation ended with the resignation, the law enforcement investigation remains active, according to the Stearns County Sheriff’s Office.

The sheriff’s investigation has not been submitted to the Stearns County Attorney’s Office.

Benson was named head coach in 2017.
