According to a probable cause document, suspect Richard Allen, who was detained last month in connection with the killings, was connected to a. 40-caliber unspent round that was discovered next to the bodies of two teenage Indiana girls.
The statement, which a judge unveiled on Tuesday, sheds insight on how investigators identified Allen and apprehended him more than five years after the deaths of Abigail Williams, 13, and Liberty German, 14, in February 2017. Allen has entered a not-guilty plea and is facing two murder charges.
In February of that year, the two girls went on a stroll along the Delphi Historic Trails, but they failed to appear when they were supposed to meet Libby’s father, according to earlier reports from the police. According to authorities, their remains were discovered the following day in a forested area close to the trail, roughly half a mile from the location where they had been let off at the Monon High Bridge.
The meager information released by officials over the years included a blurry video of a man walking and a jumbled voice recording. According to the affidavit, investigators think the evidence they’ve acquired proves Allen is the man shown on a video from Liberty’s phone forcing the girls down a hill and leading them to where they were killed.
Interviews with witnesses who were present at the location where the teens set out to hike on February 13, 2017, a day off from school, as well as the footage from Libby’s phone, are among the evidence. According to the affidavit, the man can be seen on film going behind the ladies and instructing them to “Guys, down the hill.” According to the affidavit, the two girls were dropped off there that day just before 1:50 p.m. According to the video, they ran into the man at the Monon High Bridge around 2:13 PM.
According to the affidavit, a witness subsequently reported seeing a man leaving the bridge who was “wearing a blue colored jacket and blue jeans and was dirty and bloody” and appeared to have been involved in a fight. Investigators were able to discover that the incident occurred just before 4 p.m. while the man was driving on a route close to the crime scene.
Another witness informed the authorities that she had spotted a strangely parked car at a former Child Protective Services facility. A vehicle parked at that facility that “looked as though it was backed in as to disguise the license plate” was mentioned in a tip that police received. According to the affidavit, investigators think that car matched the description of one of the two Allen had in 2017.
According to the affidavit, Allen acknowledged to an officer in 2017 that he had spent around two hours on the trail. The affidavit claims that during a subsequent interview with officials in October 2022, Allen stated that he had gone out there to “watch fish,” that he was wearing pants and a black or blue jacket, and that he has firearms that are kept at his house.
According to the document, “Investigators carried out a search warrant at Richard Allen’s residence on October 13, 2022.” Officers discovered jackets, boots, knives, and guns, including a Sig Sauer Model P226.40 caliber pistol with serial number U 625 627, among other things.
The document states that investigators discovered an unfired.40 caliber round less than two feet from one of the victims’ bodies and in between the two victims. The affidavit claims laboratory findings proved the cartridge had been fired through Allen’s Sig Sauer. According to the affidavit, when asked about that outcome, Allen denied knowing their victims or having any participation in their murders.
Although Carroll County Prosecutor Nick McLeland previously stated in court that he had “strong reason to think that Richard Allen is not the sole actor in this horrible crime,” the affidavit makes no mention of any other participants in the girls’ murders.
