On Feb. 13, 2017, 13-year-old Abigail "Abby" Williams and 14-year-old Liberty "Libby" German went to the Monon High Bridge in their home town of Delphi, Ind., while off from school for an unused snow day. After posting a few updates on Snapchat in the early afternoon hours, the girls were not seen or heard from again.
They were reported missing two hours after they didn't show up for their ride home, and their bodies were found the following day about half a mile away from the bridge.
In the more than three years since the girls' tragic murders, very little evidence has been released about the case — including the cause of death. Investigators have explained that the details of the crime scene indicate a signature, which can help them identify the killer.
With less than 3,000 residents, Delphi is a town where everyone knows one another, and the murders have greatly affected many locals.
