SHEPHERD, MI -- A gun found at a middle school in Isabella County was reportedly left by an off-duty law enforcement official, according to Shepherd police.

On Monday, March 12, a Shepherd Middle School student reported finding a handgun in a bathroom. Shepherd Police Department issued a statement on its Facebook page that read:

"A statement regarding the weapon found at the Shepherd Middle School today will be issued tomorrow. The weapon was not brought to school by a student or faculty member. It was left there on accident by an off-duty police officer (not a member of the Shepherd Police Department)."

According to a report from the Morning Sun, the weapon belonged to Isabella County Sheriff Michael Main, who inadvertently left the gun when he used the facility to change over the weekend.

Main issued a statement to The Sun apologizing for his mistake, stating that he had "no excuse for my lack of responsibility with this matter."

Attempts to reach Main has been unsuccessful.
