DELPHI, Ind. — Authorities on Monday announced an arrest in the unsolved murders of two teenage girls — a drugstore worker who has been living in the same small northern Indiana community where their bodies were found after they went on a hike nearly six years ago.
Richard Matthew Allen, 50, was arrested Friday on two murder counts in the killings of Liberty German, 14, and Abigail Williams, 13, in a case that has haunted the Indiana city of about 3,000 people.
The investigation is "far from complete," State Police Superintendent Doug Carter said at a news conference on Monday. He encouraged the community to come forward with more information, and said if any other people "had any involvement in these murders in any way, that person or persons will be held accountable."
Carroll County Prosecutor Nicholas McLeland described Allen's arrest as "a step in the right direction."
"It's concerning that he's a local guy," McLeland said.
The evidence against Allen, a licensed pharmacy technician who worked at a local CVS store, has been temporarily sealed to avoid jeopardizing the "integrity" of their investigation, authorities said. "While I know you were all expecting final details today concerning this arrest, today is not that day," Carter said.
The deaths of Libby and Abby were ruled a double homicide, but police have never disclosed how they died or described what evidence they gathered. A relative had dropped them off at a hiking trail near the Monon High Bridge just outside their hometown of Delphi, about 60 miles (97 kilometers) northwest of Indianapolis. Their bodies were found the next day, Feb. 14, 2017, in a rugged, heavily wooded area near the trail.
Libby's grandmother, Becky Patty, told reporters that Allen once processed photos for the family at the CVS store in Delphi where Allen worked. He didn't charge them for the photos, she added.
The families always knew that the suspect could have been "living right amongst us, hiding in plain sight," said Libby's grandfather, Mike Patty. "That's why we never stopped searching anywhere, because we didn't know where he was."
The Pattys wore gray shirts that read "Today is the Day ... Justice will be served for Abby and Libby," to Monday's news conference.
A judge found probable cause to arrest Allen, who entered a not-guilty plea at his initial hearing on Friday, authorities said. "All persons arrested are presumed innocent," Carter said.
Sheriff Bill Brooks in adjacent White County, where Allen is being held without bond, said he did not know whether Allen has an attorney. No murder case was listed Monday afternoon under his name in Indiana's online court system.
"We haven't closed the door on the investigation," McLeland said when asked if authorities were investigating others. "We're not presuming anything at this point."
No one answered the door Monday at Allen's house, on a street of single-family homes where some put "Keep Out" signs in their yards.
Outside the CVS store, just down Main Street from the historic courthouse square where wanted posters still seek information in the murder case, Ralph Barnaby, a Delphi resident who knows the girls' families, told The Associated Press that he'd "be more comfortable if he's indicted."
Within days of the killings, investigators released two grainy photos of a suspect walking on the abandoned railroad bridge the girls had visited, and an audio recording of a man believed to be the suspect saying "down the hill."
Authorities released an initial sketch of the suspected killer in July 2017, and then another in April 2019 based on video released in April 2019 showing a suspect walking on the abandoned railroad bridge the girls had visited. The images and audio of the suspect came from Libby's cellphone. Authorities hailed her as a hero for recording potentially crucial evidence before she was killed.
In December 2021, state police announced they were seeking information from people who had contact with someone who used a fictitious online profile to communicate with young girls. State Police said investigators determined the profile "anthony_shots" was used from 2016 to 2017 on Snapchat, Instagram and other social media platforms.
A statement from CVS said the company is "shocked and saddened to learn that one of our store employees was arrested as a suspect in these crimes. We stand ready to cooperate with the police investigation in any way we can."
"We remain devastated by these murders and our hearts go out to the German and Williams families," the statement said.
The case has been followed closely over the years by true-crime enthusiasts who have offered plenty of theories, but Carter urged people not to "subjectively interpret" the case while officers continue to gather information. "If you choose to be critical of our silence be critical of me, not the front line," he said.
Sheryl McCollum, who has appeared on television as a cold case consultant, traveled to the news conference from Atlanta after meeting the Germans at a true-crime convention. She praised the authorities for holding the facts close to their vests.
"I think the integrity of this case, and not telling every single thing they know, I think that's powerful," Sheryl said. "If you start showing your hand, you know, you can mess things up and you can tell too much ... The investigation does not stop at arrest. It really just begins. So now is when they're really going to go to work."
