Case Summary

A decades-old double homicide case that was finally solved through forensic genealogy. Two victims were found in Blackwood Forest, and the case remained unsolved for 41 years until DNA technology provided the breakthrough.

Full Description

On June 12, 1978, hikers discovered two victims in Blackwood Forest outside Portland. Despite extensive investigation, the case went cold. In 2019, investigators used forensic genealogy and DNA evidence preserved from the crime scene to identify the perpetrator, who had died in 2003. The case became a landmark example of how modern technology can solve cold cases.

Key Insights

•The successful resolution of this 41-year-old cold case underscores the transformative impact of forensic genealogy and advanced DNA analysis techniques in criminal investigations.
•The perpetrator's death prior to identification highlights the importance of preserving evidence indefinitely, as technological advancements can provide breakthroughs long after initial investigative avenues are exhausted.
•The case demonstrates the dedication and persistence of cold case units, who continually re-evaluate evidence with new methodologies.
•The initial inability to identify the perpetrator for decades suggests a lack of conventional investigative links (e.g., fingerprints in databases, known associates, or a criminal record that would have surfaced earlier).
•The location of the bodies in Blackwood Forest suggests a crime committed either opportunistically in a secluded area or by someone familiar with the terrain for disposal.

Identified Patterns

•Cases solved by forensic genealogy often involve perpetrators who were not previously in law enforcement databases (e.g., CODIS, AFIS) or who committed crimes in locations where they were not readily identifiable.
•Long-term evidence preservation is a recurring pattern in cold case successes, particularly with biological samples.
•The pattern of a perpetrator dying before apprehension is not uncommon in cold cases, emphasizing the need to identify all potential suspects, living or deceased.
•Crimes committed in secluded or natural environments (forests, remote areas) often present challenges for traditional witness identification and can lead to prolonged investigations.

Investigative Leads

•While the perpetrator is deceased, a comprehensive post-identification investigation into their life, associates, and potential other criminal activities is crucial. This includes reviewing their personal history, travel, employment, and any prior arrests or suspicious incidents that may not have been linked.
•Investigate the perpetrator's connection to Blackwood Forest or the victims' last known locations in 1978. Did they live nearby? Work in the area? Have a known recreational interest there?
•Examine the perpetrator's family tree and known associates from the time of the crime. Could there have been an accomplice, or someone who had knowledge of the crime and remained silent?
•Review all original case files for any overlooked details, witness statements, or physical evidence that might now gain new significance in light of the perpetrator's identity.
•Conduct a 'reverse engineering' of the initial investigation: knowing the perpetrator's identity, what clues might have been missed or misinterpreted in 1978?

Similar Case Characteristics

•Cases involving unidentified victims or perpetrators where DNA evidence is the primary link.
•Cold cases that remained unsolved for decades due to technological limitations at the time of the crime.
•Homicides occurring in remote or natural areas where traditional forensic evidence might be scarce or degraded.
•Cases where the perpetrator had no prior criminal record or was not in a DNA database, making traditional investigative methods ineffective.
•Cases where forensic genealogy was instrumental in generating an investigative lead that led to identification.

Recommended Next Steps

1.Conduct a full background investigation on the identified perpetrator, including their residence history, employment, associates, and any known criminal history or suspicious behavior.
2.Interview surviving family members or associates of the perpetrator, if appropriate and legally permissible, to gain insight into their character, habits, and whereabouts around June 1978.
3.Cross-reference the perpetrator's known information with other unsolved cases in the Portland area and surrounding regions from the late 1970s and early 1980s to identify potential links to other crimes.
4.Formally document the complete chain of evidence for the DNA and genealogical analysis, ensuring it meets all legal and scientific standards.
5.Prepare a comprehensive public report or statement detailing the resolution of the case, acknowledging the efforts of all involved and the role of new technologies.
