Sheriff Lamar Glover says Ricky Ducker had been accused of falsifying overtime statements by former and current members of the department.
But the sheriff announced Tuesday that a six-week investigation found no evidence to support the allegations.
Duckers was arrested on theft charges last week.
He's accused of stealing more than $15,000 worth of hunting equipment from a sporting goods store where he once worked part-time.
Ducker is currently free on a $5,000 bond.
