Allen, who was sentenced in December 2024 to a maximum of 130 years in prison, was found guilty of murdering Abigail “Abby” Williams, 13, and Liberty “Libby” German, 14, along the Monon High Bridge Trail in Delphi, Indiana, in February 2017.
A Denial Caught on Camera
In footage obtained by YouTuber Tom Webster and shared with Fox News Digital, Allen is seen speaking with investigators on Oct. 13, 2022, expressing frustration over their suspicions.
“It’s sounding more like you’re… I’m not going to be somebody’s fall guy,” Allen told investigators. “I don’t want to be someone they force into the puzzle just to close this thing.”
Allen initially interacted jovially with investigators but quickly grew defensive as questioning deepened. He was concerned about police searching his phones and personal belongings, citing a desire for privacy.
“Am I an angel of a person? No,” he admitted. “But I’m not tied to this.”
Allen also mentioned he and his wife watched crime shows and didn’t want to be wrongly associated with the case, even telling investigators he didn’t want anyone knowing about their conversation.
Evidence Mounts
Allen was questioned shortly after the 2017 murders but was mistakenly removed from the suspect list due to a clerical error. His name resurfaced years later when investigators linked a firearm found in his home to an unspent bullet recovered at the murder scene. A blue utility jacket similar to one seen in a grainy video captured by Libby shortly before her death was also found in his possession.
Despite the mounting evidence — including his gun matching ballistic evidence — Allen insisted he had no role in the girls’ deaths.
In a separate video dated Oct. 26, 2022, Allen again denied involvement while speaking to his wife.
“I know you know I didn’t do this,” Allen said. “There’s no way a bullet from my gun ended up at that scene.”
His wife questioned how the evidence could be explained, and Allen continued to maintain his innocence, accusing investigators of manipulating the case.
“They want you to think I did it,” he said.
The “Bridge Guy” Connection
During Allen’s 2024 trial, jurors were shown 43 seconds of a cell phone video Libby German had recorded. It showed an unknown man — dubbed “Bridge Guy” — walking behind the girls wearing a blue jacket and telling them: “Guys, down the hill.”
Prosecutors argued that Allen was “Bridge Guy,” citing eyewitness accounts placing him on the trail and the discovery of similar clothing at his home.
Further damaging Allen’s defense were his jailhouse confessions. According to investigators, Allen repeatedly confessed to killing the girls, even admitting he had initially planned to sexually assault them but panicked after noticing a nearby van, leading him to murder them instead.
Allen’s defense team claimed his deteriorating mental health in jail led to false confessions.
A Delayed but Devastating Break in the Case
Five years after Abby and Libby’s deaths, police executed a search warrant at Allen’s Delphi home in October 2022. They recovered a SIG Sauer P226 .40-caliber semiautomatic handgun and a .40-caliber cartridge hidden in a wooden keepsake box — ballistic matches to evidence from the 2017 crime scene.
Though Allen maintained his innocence during his initial interrogations, the overwhelming physical evidence and his later confessions ultimately led to his conviction in one of Indiana’s most haunting murder cases.
