An Alabama mail carrier has been charged after authorities say she fed at least one dog meatballs that contained nails. Officers say 47-year-old Susanna Dawn Burhans was arrested and charged with aggravated cruelty to animals. The U.S. Postal Service worker was arrested after a joint investigation by the Madison County Sheriff’s Office and the Postal Service determined she fed the nail-laced meatballs to at least one dog in New Hope. Sheriff’s Capt. Mike Salomonsky says the investigation began with a complaint nearly two weeks ago, but at least one other resident has filed a complaint. She was released from the Madison County Jail after posting $2,500 bail.
