According to NBC News, Abigail Williams, 13, and Liberty German 14, were dropped off by Liberty's elder sister at a famous trail on the afternoon of February 13, 2017. When Liberty's father arrived and parked at the trailhead to pick them up later in the afternoon, he found no trace of them. He tried calling his daughter's phone but got no answer.
The next day, on February 14, 2017, their bodies were discovered half a mile away from the trail in a wooded area.
According to court documents in 2023, Liberty and Abigail were killed with a boxcutter knife. Their throats were slit open. Liberty was found naked, covered in blood, while her clothes were found on Abigail.
An unused bullet from a .40 caliber gun was found near their bodies.
Evidence leading to Richard Allen
According to NBC News, investigators released images from Libby’s phone and an audio recording of a male voice a few days after their bodies were found.
In the aforementioned recording, a male voice said:
“Guys, down the hill.”
Investigators could not identify any suspects for years and finally sought help from the public in finding the perpetrator. In a 2019 news conference, Indiana State Police Superintendent Doug Carter stated that the heinous murderer was allegedly committed by someone within the community.
In an affidavit released in 2022, prosecutors revealed a connection between Allen and the two girls who were murdered through the bullet found near their bodies at the crime scene.
This document also stated that an unused .40 caliber bullet was found close to the bodies of the teenage victims and had come from a Sig Sauer Model P226. Incidentally, this exact model belonged to Allen since 2001 and was found during a sweep of his house.
It also revealed that Richard Allen had spoken to investigators in 2017 and confessed to being present on the Monon High Bridge Trail on the afternoon of February 13, 2017, the same day the victims went on their hike. However, Richard Allen had denied any involvement and was not considered a suspect until 2022.
Authorities discovered their possible suspect in September 2022 with the help of a volunteer file clerk who identified a document about Allen's interview in 2017.
According to the affidavit during another interview in October 2022, he had no answer for how the unused bullet from his gun landed near the two victims' bodies and he was subsequently arrested.

According to NBC News, Richard was charged with the deaths of Abby and Libby during the first hearing but he entered a not-guilty plea.
In late 2021, Kathy had posted a now-deleted picture on her Facebook profile a year before her husband's arrest. The picture showed Richard sitting in front of the suspect sketch that was being circulated for the murder case of Abby and Libby, which led the public to allegedly believe that Kathy knew about her husband's crimes.
Another post that brought all eyes to this family was a picture Kathy posted of her daughter on the Monon High Bridge in 2018, which was close to where Abigail and Liberty's bodies were discovered. The picture was taken earlier, but it garnered public attention to how Kathy could have lived with Allen for years without recognizing his alleged criminal prowess.
Furthermore, the Allens' residence is about two and a half miles from the location where the teenagers were murdered.
