Thanks to advanced DNA technology and collaborative investigative efforts, authorities have identified a homicide victim killed in Mississippi nearly four decades ago.

Officials identified the human remains found in Mississippi as William Meredith Seitz, Sr., a homicide victim killed in 1985 in Choctaw, Mississippi.

The remains, originally transferred to the Mississippi State Medical Examiner’s Office in 2023, underwent anthropological analysis, revealing they belonged to an unidentified adult male, likely aged 55 or older, who suffered a traumatic injury at or around the time of death. Despite initial efforts, his identity remained a mystery until 2024.

Earlier this year, the Mississippi State Medical Examiner’s Office and Mississippi Bureau of Investigation partnered with Othram, a Texas-based forensic DNA laboratory, to further investigate. In June, evidence was sent to Othram, where scientists developed a DNA extract to construct a detailed profile of the victim using Forensic-Grade Genome Sequencing®. Othram’s in-house forensic genealogy team then conducted genealogical and records research to generate leads.

These leads led investigators to a potential relative of Seitz. Using KinSNP® Rapid Relationship Testing, they confirmed the familial connection and identified the remains as belonging to William Meredith Seitz, Sr. The circumstances surrounding his death and the discovery of his remains remain under investigation.

This case marks the 33rd solved in Mississippi using Othram’s DNA technology. Funding for the investigation was provided by Mississippi native and philanthropist Carla Davis, whose support was instrumental in advancing the case.

Authorities hope this identification brings some closure to Seitz’s family while renewing efforts to uncover the details of his tragic death. For information on other solved cases in Mississippi, visit DNASolves.
