Police investigating the deaths of two Indiana teenagers released a voice recording captured by one of the slain girls right before she was killed: a man with a deep voice saying “down the hill.”
Police said that although the audio quality is bad, an acquaintance of the killer should be able to recognize his voice from the recording, and that Libby German—the 14-year-old girl who recorded the message—had turned on her video camera during her encounter with this man because she realized she was in danger.
"Libby had the presence of mind to turn on her video camera,” said Indiana State Police spokesman Capt. David Bursten to reporters, according to ABC News. "There's no doubt in our minds that that young lady is a hero."
Police and the FBI recovered other evidence on the phone, but are not releasing it at this time.
German and her friend, Abby Williams, 13 were reported missing after they went on a hike together in the woods on the Delphi Historic Trail.
Authorities believe a man dressed in blue jeans, a blue jacket and a hoodie may be responsible for their deaths, but they are unsure if the suspect knew the victims, according to The New York Post.
Authorities and the community are offering a combined $41,000 reward for information leading to an arrest in the case.
"We must keep our resolve for Libby and Abby, for this community and, frankly, to ensure that good trumps evil," Indiana State Police Superintendent Douglas Carter said. "And it will."
