DELPHI, Ind. – The murder of two teen girls rocked the small town of Delphi. Hundreds of investigators from across the state have been working around the clock for the last several weeks to find their killer. 

Abigail “Abby” Williams, 13, and Liberty “Libby” German, 14, disappeared on February 13 after being dropped off to go hiking near the Monon High Bridge. Their bodies were found on a piece of private property less than a mile away the next morning. 

The evidence released to the public has been minimal, but here's what we know so far: 

Social media photos give snapshot of teens’ location

On Feb.13, the same day the teens were reported missing, a photo was posted to Snapchat by Libby, showing Williams walking across the Monon High Bridge. The posting was the last time the girls were seen.

Libby’s phone turned out to be a valuable resource for clues on the teens’ deaths. On February 15, Indiana State Police released a photo that was taken from the device showing a man walking on the Delphi Historic Trail around the same time the girls were in the area. 

On February 19, they named him as a suspect in the girls' murders.

Audio clip ‘down the hill’ released by police

To generate more tips, Indiana State Police released more clues found on Libby’s phone. A suspect can be heard saying “down the hill” in an audio clip taken from a video file found on the phone. Police say it was recorded during what they believe were “criminal activities.”

Libby was heralded a “hero” by state police for having the presence of mind to begin recording. The full video from Libby's phone has not been released, nor did police elaborate on what was happening when the recording was made.

FBI seeks tips on behavioral changes

Investigators with the FBI have asked people to think back to the day the girls disappeared - do you know anyone who exhibited strange behavior that day or in the days following their murders?

They are looking for any who:

  • Changed their appearance; cut their hair, shaved when they haven't in a while or drastically changed the way they dress
  • Started abusing drugs or alcohol when they wouldn't have beforehand
  • Has become anxious or irritable
  • Took an unexpected trip after February 13
  • Canceled an appointment or social engagement on February 13 for an unexplained reason
  • Has obsessed over the Delphi murders and constantly talks about what they were doing on February 13

If you know anyone who fits any of these behavioral changes the FBI wants to know.
