Mystery solved: Stilly Doe of 1980 identified

SNOHOMISH COUNTY — On Thursday, Nov. 10, the Snohomish County Medical Examiner Office announced the identification of “I-5 Stilly Doe,” an individual who had been found in the Stillaguamish River near I-5 in 1980 but had been unidentified for the intervening 42 years. Using advanced DNA extraction techniques and genetic genealogy, investigators were able to eventually track down relatives of Othaniel Philip Ames and confirm he was their missing ancestor.
“We are incredibly proud of the long line of people in the Medical Examiner’s Office and elsewhere who continued to pursue this case from 1980 until today,” said Snohomish County Medical Examiner Dr. Matthew Lacy. “As technologies advanced and we had new tools to use, we kept making progress until we found out who this gentleman was. No matter how long it takes, we want to make sure people can be returned to their families.”
Ames had been found in the river July 23, 1980 by a fly fisherman.  On July 24, 1980, Dr. Clayton Haberman, a local pathologist, performed an autopsy and determined that the decedent did not have any apparent trauma. Dr. Haberman also found no evidence of drowning. However, there was severe coronary artery disease present, leading the cause of death to be classified as “Undetermined” with an “apparently natural” cause. But they did not know who the man was.
 After being unable to identify the decedent, he was buried at the Arlington Cemetery. Burying the identified after an unsuccessful attempt at identification was a common practice at the time. However, the Medical Examiner’s Office no longer buries people until they are definitively identified.
In 2008, Snohomish County Sheriff’s Office (SCSO) Detective Jim Scharf with the SCSO Cold Case Team, along with retired Snohomish County Superior Court Judge Ken Cowsert, began reexamining old unsolved homicides and unidentified persons cases in the county. The improvement of DNA technologies gave them hope that exhuming unidentified bodies may lead to the collection of a DNA profile that could be used to identify decedents. They were right.
In December 2017, the decedent was exhumed and named “I-5 Stilly Doe.”
After trying multiple pathways to identify him for four years and winnowing out numerous missing persons, DNA was sent to an advanced lab.
In 2021, the office began collaborating with Othram, Inc. to obtain advanced DNA profiles suitable for genetic genealogy. fully funded the laboratory work by Othram. In July 2021, Othram successfully obtained a suitable DNA extract after multiple rounds of extraction and human enrichment. 
SCMEO uploaded this profile to GEDmatch, where a few very distant matches in the 5th-7th cousin range were identified, allowing Deb Stone with Kin Forensics to begin the genetic genealogy investigation.
In May 2022, the Othram DNA profile was uploaded to Low level matches were once again found; however, they were different from the ones found in GEDmatch, allowing Deb Stone to triangulate the different matches and build additional lines back to common ancestors.
Deb Stone identified a possible matching set of great-great-great grandparents who had descendants in WA state. Deb Stone then spoke with a relative who mentioned an uncle, Othaniel Philip Ames, who went missing from Arlington in 1980 at the age of 82. He had been born on Aug. 23, 1898. Othaniel either hadn’t been reported missing or was reported missing but his records had been lost.
Othaniel’s granddaughter agreed to DNA testing that confirmed that “I-5 Stilly Doe” was in fact Othaniel Philip Ames.
Othaniel moved to Washington in 1951 with his wife and children. He worked at a paper mill and had a small dairy farm in Arlington. He was also a woodworker and a winemaker. In the early 1960s, Othaniel and his wife separated. Othaniel moved to a small cabin in the woods of Arlington.
“It is extremely satisfying to be able to reunite Mr. Ames with his family,” said SCMEO Lead Medical Investigator Jane Jorgensen. “We are extremely grateful to our partners who helped us solve this mystery. As technologies become more sophisticated, we hope to resolve all four outstanding cases and bring some peace to those families who are missing loved ones.”
 “Othram is honored to bring its expertise to bear on reuniting Mr. Ames with his family,” said Othram, Inc. CEO David Mittelman. “After 42 years of absence, our cutting-edge tools provided important keys for unlocking this mystery.  We look forward to working with others who are trying to bring resolution to their own cases.” 
The Snohomish County Medical Examiner’s Office has four additional sets of unidentified remains that they will work to identify.
