Overview
On February 13, 2017, two teenage girls, Abigail "Abby" Williams, 13, and Liberty "Libby" German, 14, were dropped off to hike along the Delphi Historic Trails near the Monon High Bridge in Delphi, a small town in Carroll County, Indiana. The two friends were reported missing after they failed to meet a relative who had arranged to pick them up that afternoon. Their bodies were discovered the following day, February 14, 2017, in a wooded area across the creek from the abandoned railroad bridge.
The case drew national and international attention, in part because Libby had used her smartphone to capture critical evidence during the abduction, including video and audio of a man on the bridge. The investigation stretched more than five years before authorities arrested a local resident, Richard Allen, in October 2022. He was convicted of both murders in November 2024 and sentenced to a lengthy prison term.
The Victims and the Disappearance
Abby Williams and Libby German were close friends and students in Delphi. On the day they vanished, the area around the Monon High Bridge Trail was a popular spot for walking and hiking. The girls were dropped off in the early afternoon during a school break and planned to spend time on the trails. When they did not appear at the agreed pickup time and could not be reached, family members became alarmed and a search began that evening.
Volunteers and law enforcement searched the trail system and surrounding woods overnight and into the next day. On February 14, 2017, searchers found the bodies of both girls. Investigators determined the girls had been abducted and killed. Authorities released limited details about the cause of death for years, citing the need to protect the integrity of the investigation, though it later emerged in court proceedings that the girls' throats had been cut.
Key Evidence and the Investigation
A pivotal element of the case was a short video Libby German recorded on her phone. The footage showed a man walking on the Monon High Bridge and captured audio of a voice saying the now widely publicized phrase, "Down the hill." Investigators released a grainy still image of the suspect and the audio clip publicly, hoping the public could help identify the man, who became known in media coverage as "Bridge Guy."
Over the following years, police released a composite sketch (and later a second, revised sketch) of the suspect and pursued thousands of tips. The case became one of the most closely followed unsolved crimes in the United States, generating extensive media coverage, online amateur sleuthing, and podcasts. Despite the publicity, the investigation produced no public arrest for more than five years, leading to criticism and frustration in the community.
A break reportedly came when investigators revisited tips, including a 2017 lead in which Richard Allen had told an officer he was on the trail that day. Authorities said evidence connected to the scene, including an unspent bullet found between the victims, was later linked to a firearm associated with Allen.
Arrest and Charges
On October 26, 2022, authorities arrested Richard Matthew Allen, a local man who had lived and worked in Delphi, including as a pharmacy technician at a CVS in the town. His arrest was announced at a news conference on October 31, 2022. Allen, who was in his late 40s at the time, had not previously been publicly identified as a suspect, and his arrest surprised many in the community.
Allen was charged with the murders of Abby Williams and Libby German. Prosecutors said an unspent .40-caliber round found at the scene was determined to have been cycled through a handgun owned by Allen. Allen pleaded not guilty. The case proceeded through a lengthy and at times contentious pretrial period, including disputes over evidence, defense filings, and the handling of Allen's detention.
Trial, Conviction, and Sentencing
Allen's trial took place in the autumn of 2024. Prosecutors presented evidence including the firearm analysis tying the unspent round to Allen's gun, the "Bridge Guy" video and audio, and statements attributed to Allen. According to court testimony and reporting, Allen made multiple incriminating statements while in custody, including admissions described by prosecutors as confessions; the defense argued these statements were unreliable and made while Allen was in a deteriorating mental state in restrictive confinement.
The defense had also advanced a theory at various points involving others and questioned the strength of the forensic evidence, but the trial centered on the prosecution's case. On November 11, 2024, a jury found Richard Allen guilty on all counts, including murder and felony murder, in the deaths of both girls. In December 2024, he was sentenced to 130 years in prison.
Allen's legal team indicated it would appeal the conviction. As of the available public record, the conviction stands while appellate proceedings move forward. The case remains officially classified as solved following the jury's verdict.
Aftermath and Legacy
The Delphi murders had a profound impact on the small Indiana community and became a defining case in modern true-crime coverage, partly because Libby German's quick thinking in recording her killer is widely credited with helping preserve crucial evidence. The families of Abby Williams and Libby German became advocates for the victims and were present throughout the long investigation and trial.
The case also prompted broader discussion about the lengthy timeline between the crime and an arrest, the role of public tip lines and online sleuthing, and pretrial procedures. Memorials and remembrances for the two girls have continued in Delphi. While the conviction of Richard Allen brought a measure of resolution, some questions raised during the proceedings have continued to be debated publicly, and the matter remains subject to the appeals process.
