Summary
In 2005, a train engineer operating a train in Yavapai County, Arizona saw a man on the tracks moments before the train struck him and killed him. The Yavapai County Sheriff's Office and the Office of the Medical Examiner responded and began investigating. Despite an exhaustive investigation, the man could not be identified and the case went cold. The man became known as Yavapai County John Doe (2005) and detail of his case were entered into the National Missing and Unidentified Persons System (NamUs) as UP95329.
In 2022, the Yavapai County Medical Examiner teamed with Othram to leverage advanced DNA testing to assist in the identification of the unknown man. Forensic evidence was submitted to Othram’s laboratory in The Woodlands, Texas. Othram scientists successfully developed a DNA extract from the remains and used Forensic-Grade Genome Sequencing® to develop a comprehensive DNA profile. Othram's in-house forensic genetic genealogy team then used the profile in a genealogical search to generate new investigative leads in the case, including the identification of potential relatives of the unidentified man.
A reference DNA sample was collected from a potential relative and compared to the John Doe's DNA profile using Othram's KinSNP® Rapid Relationship Testing. This comparison confirmed a biological relationship and the man is now identified as Darrin Allen Morgan, born on December 24, 1973. He would have have been 31 years old when he died. Morgan appears to have been raised in Illinois. It is unclear when he moved to Arizona.
Othram's casework was funded as part of the Roads to Justice (RTJ) funding program, which supports forensic genetic genealogy investigations for unidentified persons and crime victims. However, many cases remain unresolved due to a lack of available funding. Those interested in supporting the application of forensic genetic genealogy in unidentified person cases can contribute directly to DNASolves, where contributions enable critical testing that can help bring long-awaited answers to families.
The identification of Darrin Morgan represents the 11th case in the State of Arizona where officials have publicly identified an individual using technology developed by Othram. To read about other cases in Arizona that have been solved, visit DNASolves.
