A 12-person jury found the Delphi murderer guilty on four counts in connection with the slayings of Abigail "Abby" Williams and Liberty "Libby" German following 18 hours of deliberation spread across four days.
In a Carroll County courtroom Monday, Richard Allen, 52, was convicted of two counts of murder and two counts of murder while kidnapping the teenage victims, according to the Indy Star.
He sat emotionless in court as he heard the verdict read, but his mom and wife cried, ABC News reported.
Allen's wife said "this isn't over at all" following her husband's conviction, according to WTHR-TV.
The prosecution was met with a sigh of relief, while Allen's defense attorneys appeared to sympathize with him before he was remanded to jail, the station reported.
He will be sentenced Dec. 20, but will be spared the death penalty, according to Newsweek.
Best friends Abby, 13, and Libby, 14, were killed during a hike near Monon High Bridge in Delphi, Indiana, on Feb. 13, 2017. Their throats were slashed.
Prosecutors said Allen held the girls at gunpoint and used "power and fear" to order the victims down a hill where he killed them.
The next day, Libby was found dead naked, while Abby was clothed.
The "last face the girls saw" was Allen's, prosecutor Nick McLeland told jurors during the four-week trial, according to NBC News.
During police questioning, Allen maintained his innocence, but after being held in solitary confinement for 13 months, he confessed to the killings. Defense attorney Brad Rozzi attributed the "false" confession to duress.
"How much can one human endure?" Rozzi said during closing arguments last week, the network reported.
Prosecutors described Allen as the "bridge guy" who appeared in a Snapchat video found on Libby's phone. The clip captured audio of a man's voice, ordering the victims: "Guys, down the hill," according to Newsweek.
Allen, a former CVS pharmacy employee, was arrested Halloween 2022, five years after the murders.
