The body site was about 800m from the high bridge where Libby had photographed Abby the afternoon before. He said someone knows who the killer is but was keeping quiet because of “extreme fear”. “Please, please, come forward and let us know what you know,” Carter said. “There is obviously someone withholding information,” Carroll County Sheriff Tobe Leazenby told the conference. “It could very well be somewhere along the lines someone was even threatened not to reveal the identity of the killer.” Police released two very different sketches of the face of the killer, one soon after the murder and another based on an interview with a person who may have seen the culprit near Monon High Bridge on the day of the murder. In the second sketch, the man is much younger and with a full head of hair rather than a cap on his head. Supt Carter said the killer’s age had been estimated between 18 and 40 years old. Both Carter and the sheriff believe the killer has a connection to Delphi, “whether it’s an individual that previously lived in our community and knows the area where the girls were located very well, or possibly is still in our community”. “Unless someone absolutely somehow studied that [trail] in great depth, they would not know specifically where certain things were,” Sheriff Leazenby said. Another theory was that the killer worked at the nearby meatworks, which was why he was so rugged up – wearing a hoodie under his blue jacket – on such a warm day. How the girls were murdered has still not been released, as Supt Carter says, “because only the killer knows”. On Libby’s person, police found her mobile phone and on that they found video of a man on the Monon High Bridge. He is a white male with his hands in his pockets while walking. He is wearing jeans, a navy blue jacket and possibly a cap. He is walking at a fast pace across the rail bridge planks, which is no mean feat as they are separated by sizeable gaps, towards the girls. “It’s amazing we have a video, we have a still photograph, we have sound and we don’t know who this person is,” he said. The video and audio, incredibly captured by Libby as the girls were ambushed and then murdered, has been broadcast around the world and sparked thousands of tips, but led to no arrests. Both Carter, the local sheriff, other law enforcement and Delphi citizens themselves are convinced that because of the location of the girls’ abduction and murder, the killer was a local or former resident with intimate knowledge of the site. One former investigator on the case told podcast Down The Hill (DTH) that the killer – who police have now confirmed they believe is the man Libby captured on her phone – left “a lot of evidence” at the crime scene. * * * * The speculation for many is that the man rehearsed his plan, walked the route and was ready to act whenever suitable victims appeared. He passed the girls on the bridge, then turned back and when the girls noticed him walking back in their direction, Libby started recording. Gaining control of them with a knife or gun, he forced them to turn northward – and down the hill. They walked through the wood and across the creek until they reached the spot where they were found and likely murdered there.
