Summary

In August 1978, a homicide victim was found burned in a fire at a boat ramp fire at the Poole Knobs Recreation Area in LaVergne, Tennessee. Rutherford County Sheriff’s deputies responded to find the remains of an unidentified male. The homicide victim was wrapped in a blanket and had been shot four times, twice in the face. Investigators suspect he was shot at another location before being dragged to the campsite and burned. Investigators determine the victim was a white male between 30 and 40 years old. He stood 5 feet 10 inches tall, weighed approximately 160 pounds, and had medium length brown hair. The only clues to his identity were a partial set of dentures and scars on his chest from a possible heart surgery. He also had a quarter-sized mole on his torso, about two inches from his waistline.

Investigators undertook a decades-long search to determine who the man was and what happened. Fingerprints, from one hand that was not burned, were collected but generated no matches to an identity. A traditional DNA profile was created but did not produce a match in CODIS. In 2018, a facial reconstruction and a sketch of the victim were generated but, to date, have not produced any leads. More than forty years later, investigators are still looking for leads that might point to the identity of the victim and those that might be responsible for his death. Details of the case were entered into the National Missing and Unidentified Persons System (NamUs) as UP1585.

In 2020, the Rutherford County Sheriff’s Office submitted forensic evidence to Othram in The Woodlands, Texas to determine if advanced DNA testing could help identify the victim. At Othram, scientists successfully developed a DNA extract from the provided evidence, which presented significant challenges given the burnt condition of the man's remains. After the successful extraction of DNA, Othram scientists used Forensic-Grade Genome Sequencing® to build a comprehensive DNA profile for the victim. Othram's in-house forensic genetic genealogy team used the profile in a genetic genealogy search to develop new investigative leads that were returned to law enforcement.

Using this new information, a follow-up investigation was conducted leading investigators to potential relatives of the victim. Reference DNA samples were collected from a relative and compared to the DNA profile of the unidentified man. This investigation led to the positive identification of the murder victim, who is now known to be 52-year-old Jessie Lee Williamson. An investigations into Williamson's death is ongoing. Anyone with information about the victim is encouraged to contact Detective Sgt. Richard Brinkley with the Rutherford County Sheriff’s Office at (615) 904-3045.

A portion of Othram's casework costs associated with the advanced DNA testing and forensic genetic genealogy completed in this case was contributed by donors through a DNASolves® crowdfund. We are grateful to everyone that helped crowdfund this case and other DNASolves cases. Remaining costs for the advanced DNA testing and forensic genetic genealogy used in this case was provided by NamUs, a national program that assists the criminal justice community with the investigation and resolution of missing, unidentified, and unclaimed persons cases across the United States and its territories. NamUs is funded and administered by the National Institute of Justice (NIJ) and is managed through a contract with Research Triangle Institute International (RTI). Othram is grateful for the support of RTI, NamUs, and the NIJ.

Individuals who have taken a consumer DNA test can aid ongoing forensic investigations by contributing their DNA to the DNASolves database. Expanding the number of available DNA profiles increases the likelihood of successful identifications, helping to reunite families with their missing loved ones and resolve cases that have remained unsolved for years.

The identification of Jessie Lee Williamson represents the 27th case in the State of Tennesse where officials have publicly identified an individual using technology developed by Othram.
