The Monroe Police K9 is retiring.  K-9 Gunner signed off for the last time at 11pm Wednesday.  Gunner was with the Monroe Police Department for five and a half years. He has been with his handler, Officer Jeffrey Loomis, since June 15th, 2011 and he's worked on many noteworthy cases.  Last year Gunner was rushed to the veterinary hospital with a life threatening illness and he was able to return to work just weeks later.  Monroe Police say Gunner will be sorely missed by the men and women of the department and they wished him a happy and long retirement.
