In 2023, the Sonoma County Sheriff’s Office and California Department of Justice partnered with Othram to employ advanced forensic DNA analysis to try to identify the woman. Forensic evidence was sent to Othram and Forensic-Grade Genome Sequencing® was used to build a comprehensive DNA profile suitable for forensic genetic genealogy. Othram’s in-house forensic genetic genealogy team then used the profile in a genetic genealogy investigation to develop new leads in the case. During the course of an investigation, detectives were able to confirm the identity of the unknown woman as Deborah Mitchell Cordier, who was born on July 25, 1952.
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.
Individuals who have taken a consumer DNA test can aid ongoing forensic investigations by joining the DNASolves database. Expanding the pool of available DNA data increases the likelihood of successful identifications, helping to reunite families with their missing loved ones and resolve cases that have remained unanswered for years.
The identification of Deborah Cordier is the 58th case in the State of California where officials have publicly identified an individual using technology developed by Othram. Visit DNASolves to learn about other California case, where your support can help bring long-awaited answers to families.
