Murder down the hill. I'm Jason Horton. I'm Rebecca Lee and this is Ghost Town.

A potential new lead in the unsolved murders of 13-year-old Abby Williams and 14-year-old Libby

German. Those two eighth grade girls last seen snapchatting on a hiking trail in Delphi,

Indiana in 2017. But despite this video and audio of the suspect taken from Libby's cell phone,

just four years ago two teenage girls were murdered in Delphi, Indiana. The case is horrifying,

but the evidence collected by one of the very brave young victims makes it really intriguing,

frustrating, and also perhaps solvable. Today I'm going to be talking about the murder of

Abby Williams and Libby German, also known as the Delphi murders. 13-year-old Abigail J,

Abby Williams and 14-year-old Liberty Rose Lynn, Libby German were best friends and pretty typical,

Libby's older sister, Kelsey, on Country Road 300 North. The girls didn't have school that day,

and it was really nice afternoon. Again, in Indiana, that doesn't happen very often,

so they decided to take a hike on the city's historic deer creek trails east of Delphi.

At 207 pm, Libby posted a photo of Abby walking on the Minone High Bridge over deer creek.

This was the last anyone would hear from either of them. And the photo itself, too, you can find it

online. It's really sweet, and it's just, it's so innocent. It's like two girls exploring the

woods, which is something I did as a child, and I'm sure a lot of people did, too. Around noon,

about half a mile from the high bridge where Libby had photographed Abby the afternoon before,
