An ongoing investigation by the F-B-I into activities at the Horse Cave Police Department in Hart County has resulted in some personnel changes. According to Horse Cave Mayor Randall Curry officer David Graves is now the acting Chief of the Horse Cave Police Department. He replaces former Chief Sean Henry who, along with officer Chris Trulock, have been placed on administrative leave without pay. Meanwhile Horse Cave police officer Larry Martin has been terminated. Martin was employed with restrictions placed on his law enforcement duties as a result of being under investigation concerning his activities when he was a deputy sheriff in Monroe County. Horse Cave city officials say they still know very few details about the F-B-I probe into police department activity in Horse Cave which started in early March of 2018 with potential evidence being removed from the Horse Cave Police Department in Hart County.
