DNA Analysis Helps Police Identify Man’s Remains 20 Years After They Were Discovered Near a Cemetery

Skeletal remains discovered in a wooded area near a Portland cemetery more than two decades ago have been definitively identified as belonging to Robert Lee Horton, who went missing in December 2004. The identification was made possible through innovative DNA testing methods, according to the Oregon State Police.

Horton, a 47-year-old man who moved from Hawaii to Portland in the same year he disappeared, was reported missing after his family noted that he had not claimed personal items sent to him following his relocation. His remains were unearthed on December 19, 2004, by two individuals near Riverview Cemetery in Southwest Portland. An investigation was initiated, led by the Portland Police and a medicolegal death investigator from Multnomah County.

When discovered, the remains were found in proximity to various items, including cooking pans, clothing, and a makeshift fabric shelter. These initial discoveries, while indicative of an individual living in the woods, did not yield a clear cause or manner of death, despite an autopsy conducted by the Oregon State Medical Examiner’s office shortly thereafter.

In 2010, investigators submitted a DNA sample from the remains to the University of North Texas Center for Human Identification for Short Tandem Repeat (STR) sequencing. The sample was subsequently entered into the Combined DNA Index System, where it remained inactive for nearly a decade. State officials continuously monitored the data for any emerging leads but saw little progress during this time.

In 2018, a breakthrough occurred when the medical examiner’s office obtained a grant aimed at applying new genetic testing methodologies to cold cases. Horton’s remains were included in the initiative, and through the work of Parabon NanoLabs, an additional bone sample yielded a Single Nucleotide Polymorphism (SNP) DNA profile. This created new possibilities for familial matching.

A significant development occurred in 2022, when a DNA genetic genealogy report indicated potential links between the remains and Horton’s distant relatives. Despite this promising lead, the case was not reopened until 2025, when the medical examiner’s office revisited the findings with Parabon NanoLabs to explore more potential leads. Eventually, this collaborative effort facilitated Horton’s identification.

Family members contributed to the resolution of the case by providing a DNA sample from Horton’s mother, which was further analysed at Parabon NanoLabs. Following comprehensive testing, authorities confirmed by April that the skeletal remains were indeed those of Robert Lee Horton.

Once the identification was established, law enforcement officials informed Horton’s family of the findings. Sadly, his mother passed away shortly thereafter, underscoring the bittersweet nature of the resolution for the family.

Portland Police Chief Bob Day commented on the identification, stating that while the passage of time cannot mitigate the heartache experienced by Horton’s loved ones, the resolution may offer a degree of closure. He expressed hope that the identification would provide the answers the family has long sought.

Furthermore, the case demonstrates the power of interagency cooperation in solving cold cases. Hailey Collord-Stalder, the State Forensic Anthropologist, praised the collaborative efforts that culminated in the identification of Horton’s remains. She emphasised the significance of the advanced genetic analysis from Parabon NanoLabs and acknowledged the dedicated work of both the Multnomah County Medical Examiner’s Office and the Portland Police Bureau.

The successful identification of Robert Lee Horton’s remains not only resolves a long-standing mystery but also highlights the importance of advances in forensic science and collaborative investigation efforts in bringing closure to families enduring the pain of unresolved loss.
