BANGOR, Maine (AP) — A detective who put the Bangor Police Department on the social media map is retiring to write a book. Lt. Tim Cotton used humor on Facebook to put a human face on police work, and he created the viral “Duck of Justice” when he rescued a faux waterfowl from a trash bin. Visitors routinely drop by the police department to have their picture taken with the duck. In his retirement, Cotton will continue posting to the Duck of Justice’s Facebook page for the police department while pursuing his writing career.
