INDIANAPOLIS (WISH) — Former FBI agent Doug Kouns says the voice in the Delphi Murders‘ “bridge guy” video sounds different than the version released in 2017 by police.

Richard Allen, at age 52, was found guilty in November of two counts of murder and two counts for felony murder for the deaths of 13-year-old Abigail “Abby” Williams and 14-year-old Liberty “Libby” German. The girls’ bodies were found near the bridge near Delphi on Feb. 14, 2017, a day after they went missing.

Libby captured the 43-second video at 2:13 p.m. Feb. 13, 2017, while on the former railroad bridge that’s now a pedestrian bridge in Carroll County. The video was played during Allen’s weekslong trial in October and November before a jury of Allen County residents, but the recording had not previously been released for wider view beyond the courtroom. Allen’s defense team said Wednesday on X that it had shared the video on the website rickallenjustice.com.

The full video was widely released Wednesday night, News 8 has reported. Previously, only people associated with the investigation, and the people in the trial courtroom had watched the full video.

Indiana State Police, while searching for a suspect in April 2019, had played a portion of what became known as the “bridge guy” video. A voice in the video ordered, “guys, down the hill,” investigators said.

The former FBI told I-Team 8 on Thursday that the tone of the voice of the “bridge guy” telling the girls, “down the hill,” is what he noticed as different.

Kouns said of the original video police released, “It sounded more like a, almost like a disguised voice. You know, when you’ve got a witness that they’re trying to change their voice for protection and it’s like, ‘down the hill.’ It doesn’t sound as natural or real as it does in this new release.”

When Kouns looked at that, did he think that voice is definitively Allen?

“I don’t personally believe so,” Kouns said.

Kouns also picked up on something else in the video: Abby and Libby talking about there not being a path.

“There’s no path going there so we have to go down the hill,” said one of the girls in the newly released video.

Kouns said, “I think they were planning on going down the hill anyway, and she obviously sensed some danger, otherwise probably not would have been recording like that in a surreptitious manner. It’s just very sad. It makes these little girls seem even more human when you see them in this context. It’s not just a picture on TV, or somebody talking about them. It just makes it more real and tragic.”

A special judge in December sentenced Allen to 130 years in prison for the murders, after a weekslong jury trial.

The video came out a day after Allen’s defense attorney’s filed a motion with the Indiana Court of Appeals to appeal Allen’s conviction.

Kouns didn’t expect the release of this video to have much impact on Allen’s appeal. “I didn’t see anything new today that would help one way or the other with the investigation,” Kouns said Thursday.
