I firmly believe that they knew they were in trouble as Libby recorded a man walking on the bridge as well as audio recording of him talking and telling them to go "down the hill". Cell phone pictures and video have aided police in the investigation, but have not led to the killer yet. Someone knows this person and someone knows what happened to these two young ladies and a killer still walks free!
April 20, 2019 Indiana State Police released a new sketch of the person they are searching for. This sketch is very different from the one released a couple of years ago and so please take a look at this photo.
