In announcing the arrest, however, Delphi police said they would not be releasing the probable cause affidavit leading to Allen’s arrest, nor would they discuss any information relating to the investigation or arrest.
“This investigation is far from complete,” Indiana State Police Superintendent Doug Carter said during a news conference, adding that the “time will come when additional details can be released.”
Carroll County Prosecutor Nicholas McLeland added that “per the court order, we cannot talk about the evidence that’s in the probable cause” affidavit, but said a public hearing would be held to discuss unsealing the documents.
As to why the documents are being sealed – unusual in most cases – McLeland said it was “because this case is still open” and that there was “extra scrutiny.”
“We haven’t closed the door on the investigation,” McLeland said. “We’re going to continue to take tips, take any information that anybody has.”
Allen, the man who was booked into the Carroll County Jail for the murders, is a married father whose name previously had never been tied to the case, The Independent reported. He also had reportedly posed for a smiling selfie in front of a police sketch of the suspect in the murders.
Allen has been charged with two counts of felony murder.
On February 13, 2017, 13-year-old Libby German and her best friend Abby Williams went for a walk along the Monon High Bridge in Delphi, Indiana. The next day, their bodies were found in a creek about a mile away.
After their bodies were found, police pulled evidence from Libby’s phone, which included photos of a potential suspect, as well as an audio recording of a man saying “down the hill.” Police released two sketches of potential suspects, as well as a short audio clip. The Murder Sheet Podcast was also able to obtain court documents this summer that showed an FBI agent sought a search warrant for the property where the girls’ bodies were found, a property owned by Ron Logan.
The search warrant revealed that the audio recording containing the “down the hill” clip was actually 43 seconds but wasn’t fully released to the public. In addition, investigators reportedly found a large amount of blood where the girls’ bodies were found and believed the perpetrator must have gotten blood on their hands or clothing. Police also suggested that the perpetrator may have taken a “souvenir” from the girls and “moved and staged” their bodies.
The warrant also suggested Logan fit the physical description of the man seen in photos on Libby’s phone and that he had lied about his alibi. Logan has never been charged with a crime relating to the murders and has never been named a suspect.
