The man found dead Nov. 19 in a house on Kirkland Circle was 24-year-old Lance Monroe Cole, according to Barrow County Sheriff Jud Smith.
A family member returning home after working an overnight shift in Gwinnett County discovered the body.
The sheriff said the GBI crime lab would verify the cause and time of death, but he said that information would not be released to the public until a suspect is arrested. Investigators are pursuing leads concerning suspects. Smith said his staff spent 11 hours processing the crime scene.
"We are going to be very thorough in our investigation," he added.
