Indiana authorities urged the public Wednesday to keep passing on tips in the slayings of two teenage girls killed during a hike, saying on the 2-year anniversary of the crime that the next tip could help solve the case. Liberty German, 14, and Abigail Williams, 13, vanished on Feb. 13, 2017, after a relative dropped them off for a hike near an abandoned railroad bridge near their hometown of Delphi, about 60 miles northwest of Indianapolis, during a day off school. They failed to show up at a pre-arranged pickup location, and their bodies were found the next day in a rugged, wooded area following a search. Police have disclosed few details in their investigation and have not said how the teens were killed.
Carroll County prosecutor Nicholas McLeland said Wednesday that the case remains under active investigation and he's confident it will eventually be solved. He said more than 38,000 tips have been received to date, but urged the public to keep sending tips to authorities if they believe the information could help investigators. "That could be the missing piece that we're waiting on, that ties everything together," he said. "Any little tip could be the piece that we need." Within days of the killings, investigators released two grainy photos of the suspect walking on the abandoned railroad bridge the girls had visited, and an audio recording of a man believed to be the suspect saying "down the hill." A reward of more than $230,000 is being offered for information leading to an arrest or arrests and convictions in the teens' killings. (Police have called Liberty German a hero for having the presence of mind to record the suspect.)
