Police Believe Person Who Killed Indiana Teens Is Hiding in Plain Sight

Authorities released new audio and video as they continue to hunt for the killer of two teenage girls in Delphi, Indiana. More than two years after Abigail "Abby" Williams, 13, and Liberty "Libby" German, 14, were found dead off a rural hiking trail near Delphi on Feb. 14, 2017, authorities have yet to catch their murderer. The Indiana State Police held a press conference to update the public on the "new direction" the investigation has taken.
