Mary "Frankie" Harvey (Jack of Hearts, Massachusetts)

In November 1980, 13-year-old Frankie Harvey was shot and left to die in a gravel pit in Wrentham, Massachusetts. The Rhode Island girl had vanished on Thanksgiving and while her family was waiting for her to show back up, police in Massachusetts were trying to figure out who she was. Ballistics testing later showed that her murder was connected to the murder of Frank Cannon in Pawtucket, Rhode Island … but no real investigation involving both cases has been done until now.
