Libby, 14, and Abby, 13, went missing while hiking near the Monon High Bridge. Their bodies were found less than a mile from where they were last seen alive.
Indiana State Police released a picture of a suspect, which was taken by Liberty on her cell phone. She also captured a man's voice saying "down the hill" during what police call "criminal activity." You can listen to that recording and see the photo below.
Indiana State Police ask anyone who recognizes the man or the voice, or who may have any other information, to call the Tip Line at (844) 459-5786 or 1-800-225-5324 (800-Call FBI). Tips can also be emailed to Abbyandlibbytip@cacoshrf.com. Information can be reported anonymously.
