DELPHI, Ind. — A former drugstore worker in the small Indiana community of Delphi was found guilty of murder on Monday in the killings of two teenage girls who vanished during an afternoon hike.

Jurors convicted Richard Allen of two counts of murder and two additional counts of murder while committing or attempting to commit kidnapping in the 2017 killings of Abigail Williams, 13, and Liberty German, 14.

Allen wasn’t arrested for five more years, while the case drew outsized attention from true-crime enthusiasts. His trial followed repeated delays, a leak of evidence, the withdrawal of Allen’s public defenders and their reinstatement by the Indiana Supreme Court.

Reporters inside the courtroom said Allen, 52, showed no reaction as the verdict was delivered, but he looked back at his family at one point. Allen is scheduled to be sentenced on Dec. 20. He could face up to 130 years in prison.

Outside the courthouse, people on the sidewalk began to cheer as word of the verdict spread.

Indiana State Police spokesman Capt. Ron Galaviz told The Associated Press that the judge’s gag order remains in place and he believes it will until Allen is sentenced. Allen’s lawyers left the courthouse Monday without making statements.

A special judge oversaw the case — Superior Court Judge Fran Gull who along with the jurors, came from northeastern Indiana’s Allen County. The seven women and five men were sequestered throughout the trial, which began Oct. 18 in the Carroll County seat of Delphi, the girls’ hometown of about 3,000 residents in northwest Indiana where Allen also lived and worked.

Carroll County Prosecutor Nicholas McLeland noted in his closing argument that Allen had repeatedly confessed to the killings — in person, on the phone and in writing. In one of the recordings he replayed for the jury, Allen could be heard telling his wife, “I did it. I killed Abby and Libby.”

McLeland also said Allen is the man seen following the teens in a grainy cell phone video recorded by one of the girls as they crossed an abandoned railroad trestle called the Monon High Bridge.

“Richard Allen is Bridge Guy,” McLeland told jurors. “He kidnapped them and later murdered them.”

McLeland said it was Allen’s voice that could be heard on the video telling the teens, ” Down the hill ″ after they crossed the bridge on Feb. 13, 2017. Their bodies were found the next day, their throats cut, in a nearby wooded area.

An investigator testified that Allen told him and another officer that on the day the teens vanished, he was wearing a blue or black Carhartt jacket, jeans and a beanie — clothing similar to what the man recorded on the bridge wore.

McLeland said an unspent bullet found between the teens’ bodies “had been cycled through” Allen’s .40-caliber Sig Sauer handgun. An Indiana State Police firearms expert told the jury her analysis tied the round to Allen’s handgun.

But a firearms expert called by the defense questioned the analysis, and attorney Bradley Rozzi dismissed it as a “magic bullet,” saying investigators had made an “apples to oranges” comparison of the unspent round to one fired from Allen’s gun.

Allen was arrested in October 2022. He had become a suspect after a retired state government worker who volunteered to help police in the case found paperwork in September 2022 showing that Allen had contacted authorities two days after the girls’ bodies were found. That paperwork indicated that Allen had told an officer he had been on the hiking trail the afternoon the girls went missing, according to testimony.

Allen’s defense argued that his confessions are unreliable because he was facing a severe mental health crisis while under the pressure and stress of being locked up in isolation, watched 24 hours a day and taunted by people incarcerated with him. A psychiatrist called by the defense testified that months in solitary confinement could make a person delirious and psychotic.
