Found Near a Cemetery, Nameless for 20 Years—DNA Finally Reveals Who He Was

More than two decades after skeletal remains were discovered in a wooded area of Southwest Portland in 2004, authorities have identified them as belonging to Robert Lee Horton, thanks to advances in forensic DNA technology.

Horton would have been 47 years old at the time of his death, experts said.

The Oregon State Police (OSP) announced the identification in a statement on Facebook, saying the breakthrough was made possible through improved DNA analysis, sustained investigative efforts, and collaboration among multiple agencies.

“After more than 20 years, the Oregon State Medical Examiner’s Office and our partner agencies have positively identified the remains found in Southwest Portland in 2004 as Robert Lee Horton,” the statement read.

Officials acknowledged the emotional weight of the development, adding, “While we recognize the profound loss felt by Robert’s loved ones, we hope this news brings a measure of closure.”

On December 19, 2004, two individuals exploring the area near Riverview Cemetery discovered human remains later determined to be Horton’s. They notified local law enforcement.

Personnel from the Portland Police Bureau, along with a medicolegal death investigator from Multnomah County, responded and initiated an investigation, authorities said.

At the scene, investigators located not only skeletal remains but also a fabric lean-to, cooking pans, food items, and clothing. The clothing was collected as evidence, while the remains were transported to the Oregon State Medical Examiner’s Office for further examination.

In 2010, a DNA sample was submitted to the University of North Texas Center for Human Identification for Short Tandem Repeat (STR) analysis. The resulting profile was entered into the Combined DNA Index System (CODIS) and the National Missing and Unidentified Persons System (NamUs). However, no matches or leads were identified.

In 2018, the Medical Examiner’s Office received a National Institute of Justice (NIJ) grant aimed at improving forensic DNA capabilities in unresolved cases. Horton’s case was selected for advanced testing, including DNA phenotyping and investigative genetic genealogy through Parabon NanoLabs. A new bone sample was submitted, and a Single Nucleotide Polymorphism (SNP) profile was successfully developed.

By January 2022, a DNA Snapshot® Genetic Genealogy Report had been completed. Although numerous potential relatives were identified, they were only distant connections.

In late 2025, the Medical Examiner’s Human Identification Program re-engaged Parabon NanoLabs to determine whether new leads had emerged. The case was reopened, and by early 2026, investigators identified Robert Lee Horton, born in 1957, as a likely match. He had been missing since 2004.

Further investigation revealed that Horton had been living in Hawaii before relocating to Portland in 2004. His family became concerned after losing contact with him and noticing that mail and other items went unclaimed. Detectives contacted surviving relatives and obtained a DNA reference sample from Horton’s elderly mother, the Oregon State Police said.

In February 2026, the sample was submitted for analysis. By April, a Kinship Inference Report confirmed with 100 percent certainty a parent-child relationship between the reference sample and the unidentified remains.

Horton’s family was promptly notified of the identification. Tragically, his mother passed away shortly thereafter.
