As Sgt. Dan Franklin moved up the ranks and through various departments in the Hall County Sheriff’s Office, he asked to keep one particular case: the slaying of Hannah Truelove, which happened four years ago this week. “I asked to keep Hannah’s case because it was important to me and I wanted to make sure it got the attention that it needed,” he said. Truelove, a 16-year-old Gainesville High School student, was stabbed multiple times, according to investigators.
