The Delphi double murder suspect has confessed to killing his two alleged victims on at least five separate occasions since his arrest, according to newly-unsealed court documents that also reveal they were killed with a sharp object.
Richard Allen, 50, is accused of killing Libby German, 14, and Abby Williams, 13, while they were hiking through Indiana’s Delphi Historic Trails on 13 February 2017.
Prosecutors claim that Allen has made several phone calls to his wife, Kathy, and his mother while at the Indiana Department of Corrections, in which he admits to killing the two girls.
Documents also revealed that both girls had wounds caused ‘by a sharp object’ and ‘articles of clothing were missing.’
The filings said: ‘They also determined that articles of clothing from the girls were missing from the scene, including a pair of underwear and a sock.’
Libby’s iPhone was discovered under her body, and contained the 43-second video that helped investigators piece the case together.
Allen County Judge Frances Gull has released 118 documents in the case, with just 19 remaining sealed.
Court documents also show that on one occasion when Allen admitted to the murders, April 3 this year, his wife ended the call abruptly.
Details of Allen’s other alleged confessions have not been shared. He is said to have broken the tablet he used to make texts and send phone calls, and is not believed to have called or texted anyone on it in months.
Search warrants also show that investigators searched his home in Delphi, including outbuildings, a shed and Allen’s car, looking for firearms and knives.
They also scoured the home for electronic devices, clothing and a specific cell phone.
Law enforcement recovered numerous items, including boots, multiple knives and sweatshirts, multiple cell phones, an iPod, a hard drive, laptop and other electronics.
An affidavit released in November 2022 shows that an unspent .40 caliber round was found between the teenagers’ bodies, and it was later linked to Allen’s Sig Sauer Model P226 firearm through forensic evidence.
Prosecutors believe the gun links Allen directly to the case, after forensics determined a bullet found next to the girl’s bodies had cycled through his gun.
Allen’s defense attorneys are contesting that evidence from the Indiana State Police Laboratory.
They have also argued that he is under great physical and mental duress because of his incarceration – arguing that his admission of guilt is unreliable.
Prosecutors have since countered the claims, saying that Allen’s behavior has changed drastically since his admission on April 3.
Court documents have revealed that he has not made a single phone call since the admission, and has undergone a psychiatric evaluation.
They say by April 14, Allen began to eat and sleep regularly, with his behavior returning to normal. When he was first interviewed in the case in 2017, he told officers that he had been on the scene at the time of the murders to ‘watch the fish’ in the river.
Authorities then chose to re-interview him on the matter in October 2022, and scour his home for evidence.
Allen also admitted that he had clothing similar to that worn by the ‘Bridge Guy’ captured in the infamous 43-second clip.
