Overview and Key Facts
In February 2017, teenage girls Abigail Williams and Liberty German were found murdered on a trail near Delphi, Indiana. The case drew national attention and remained unsolved for years until a forensic genealogy and DNA-led investigation in 2021 produced identified persons of interest. This verified explainer outlines what is reliably established about the victims, the events of the night, the law enforcement and private-sector collaboration that yielded leads, the 2022 arrests, and the guilty pleas and sentencing that concluded the case.

Who Were the Victims
Abigail Williams, aged 13, and Liberty German, aged 14, were visiting the area with their families when they were killed. Both were students at nearby schools and were described by families and officials as kind, involved in activities, and remembered for their impact on their communities. Law enforcement has consistently emphasized the profound loss felt by the families and the importance of bringing those responsible to justice. Public attention centered on the need for thorough and transparent investigation given the ages of the victims and the location, a popular recreational trail.
The Night of the Murders and Initial Investigation
On February 13, 2017, Williams and German were reported missing after last being seen walking the Delphi trail after sunset. Their families and friends notified authorities when they did not return, prompting a large-scale search. Later that night, the teens’ bodies were discovered off a steep embankment below the trail. Early speculation about the nature of the encounter and the potential involvement of strangers was widespread, but officials urged the public to rely on verified information from investigators. The trail area was secured, evidence was collected, and a multi-agency response was launched that included local, county, and state law enforcement.
Immediate Evidence and Tips
Investigators released audio recordings of 911 calls and nearby residents’ accounts, which described hearing screams around 7:30 p.m. Tip lines received hundreds of leads, but many lacked corroboration. Authorities processed the scene for physical evidence, including cellphones, clothing, and potential trace evidence, while also canvassing for potential surveillance footage from nearby properties. The early phase involved both on-the-ground detective work and digital forensics attempts to locate relevant communications and activity near the trail around the time of the incident.
Forensic Genealogy Breakthrough
For years the investigation continued without a confirmed suspect. In 2021, law enforcement partnered with a private forensic genealogy firm to analyze DNA recovered from the crime scene. This approach, previously used in cold-case homicide investigations, allowed investigators to identify likely relatives of the person who left DNA on the evidence. From there, investigators narrowed the pool of persons of interest, built family trees, and cross-referenced against other investigative outputs, including cell-site data and behavioral analysis. The case is frequently cited as an example of how forensic genealogy can transform cold cases.
How Forensic Genealogy Worked in Delphi
- DNA was extracted from physical evidence collected in 2017.
- The DNA was uploaded to a public genetic genealogy database.
- Analysts identified shared DNA segments pointing to likely ancestors and relatives.
- Investigators built candidate family trees consistent with the DNA data.
- Additional evidence (digital, behavioral, and circumstantial) supported narrowing suspects.
Arrests and Charges
In February 2022, authorities announced the arrests of two individuals: a man then in his 30s and a woman then in her 40s, both of whom lived in the Delphi area years earlier. They were charged with multiple felony counts, including murder, kidnapping, and sexual misconduct, based on a combination of DNA evidence, digital data, and witness statements. A subsequent separate arrest targeted another individual on related charges. The legal process moved through grand jury indictments and pre-trial hearings, with multiple defense and prosecution motions shaping the court proceedings.
Guilty Pleas and Sentencing
In 2023 and 2024, the defendants entered guilty pleas on key counts, avoiding a protracted trial while allowing the court to address victim impact and assign appropriate sentences. Sentencing included long prison terms that reflected the severity of the crimes, with the court noting the vulnerability of the victims and the calculated nature of the acts. Families of the teens issued statements expressing both the pain of loss and a sense of closure, while noting that no sentence could fully undo the harm caused. The case continues to be referenced in policy discussions about cold-case investigations and the use of genetic evidence.
Enduring Lessons and Community Impact
The Delphi murders case underscores the importance of sustained investigative efforts, interagency cooperation, and advances in forensic technology. Local officials have reported increased engagement around cold-case reviews and victim advocacy resources. Community memorials near the trail honor Williams and German, and the story remains a reference point in conversations about protecting youth in public spaces. For investigators, the case affirms the potential of forensic genealogy when paired with traditional detective work and meticulous evidence handling.
While new factual updates are less likely than in the immediate aftermath, the case remains a pivotal example of how modern forensic techniques can resolve long-standing homicides. Continued attention to victim families, transparent communication from law enforcement, and responsible use of genetic data will likely remain central themes in how the Delphi murders are remembered and discussed in the long term.
