A new video released by supporters of Richard Allen, convicted of killing Abigail “Abby” Williams and Liberty “Libby” German in 2017, shows the last moments of the girls, where they sound nervous and appear to be in silent panic.

Libby, 14, and Abby, 13, were found slain a day after they disappeared during a hike on a trail in Delphi, Ind. in February 2017.

Allen was convicted in November 2024 of four counts of murder in their killings and was sentenced to 130 years in prison.

The investigation — and later Allen’s conviction — hinged in part on a damning video recorded on Libby's phone showing a man following the two on an otherwise isolated trail.

The shadowy "Bridge Guy," as he came to be known, was seen in a brief video released publicly showing him following the girls on a bridge. He was not identified for five years until Allen's arrest in 2022.

Now, a longer video, shared by Allen’s supporters, shows more of the girls’ last chilling final moments.

The 43-second video shows Libby pointing the camera towards Abby, who is being followed by "Bridge Guy" in the background.

Abby is heard whispering at the camera "Is he?" before her voice becomes inaudible. Libby sniffles before turning the camera and walking ahead while Abby says something else, also inaudible, in the background.

"See, this is the path," Libby says, her camera pointing to the ground, before her voice drops, "that we're on." Abby rushes past the camera at this point.

"Umm, there's no path going there," Libby says, the camera still pointing towards the gravel on the road, "so we have to go down here."

One of them is heard panting, and another one is heard sniffling amid their footsteps on the gravel.

Then "Bridge Guy" is heard saying the infamous lines that became synonymous with the case: "Guys, down the hill." Then the video abruptly ends.

The video was released on a website made by Allen's supporters, who claim to be working on his "post-conviction legal work" following what they say was a “wrongful” conviction.

Allen's appellate lawyer tells PEOPLE their team is not linked to the website and themselves do not have a copy of the newly released video.

"[The video] doesn't change the fact that he was unable to challenge the state's case or present evidence about any other suspects," Stacy Uliana tells PEOPLE.

During the trial, Allen's defense tried to argue the girls were killed in a ritualistic sacrifice by Odinists, members of a Norse pagan religion linked with White nationalism, the Associated Press and CNN previously reported, citing defense motions.

The theory was not allowed in a court after a judge ruled there was a lack of evidence to support the claim, per court records.

The slain girls were best friends, Libby's grandfather Mike Patty told PEOPLE following the murders.

They spent time in class together at the local middle school, Patty previously said. Outside school, the two were known to play sports together or go hiking Delphi’s community trails.
