The Gwinnett County Medical Examiner’s Office recently found four more bones belonging to an unidentified skeleton found in a wooded area of Buford in 2015.

A theory about the remains has also emerged.

“The Medical Examiner is theorizing that the man may have been associated with the contractors responsible for the construction of nearby subdivisions,” said Gwinnett County Police Department Cpl. Deon Washington.

The skeleton was found July 2015 in a wooded area between Satellite Boulevard and Buford Highway. Washington said the remains already been there “several years” when they were found.

That makes identifying the body a bit more difficult. Officials still haven’t found any personal effects for the man and haven’t been able to determine a cause of death.

The medical examiner estimates the man was between 25 and 40 years old when he died. He likely stood anywhere from 5-foot-3 to 5-foot-7. His teeth had several composite fillings and he had at least one root canal involving a tooth on the lower jaw.

Washington said previously the medical examiner confirmed the remains do not belong to Justin Gaines, an 18-year-old Snellville native who has been missing since November 2007 when he was seen leaving Wild Bills nightclub in Duluth.

Everything else about the skeleton remains a mystery, but officials haven’t given up on the case.

Kelly Lawson, a forensic artist from the GBI, released a reconstruction sketch in February of what the man may have looked like when he was alive. She had to guess on the hair color, hair length and skin tone.

“We ask that people take a second look at the sketch and report any tips immediately,” Washington said.

Anybody with information on the case should contact GCPD detectives at 770-513-5300. Tipsters can remain anonymous by contacting Crime Stoppers at 404-577-8477 or by texting tips to 274637.

Crime Stoppers tipsters can receive up to $2,000 for information leading to an arrest and indictment in this case.

At first I thought this was a new sketch for the unidentified male found in Atlanta in 1999, but it isn't. Probably just a coincidence.
