Gwinnett County police are investigating the "suspicious" death of a man whose body was found early Monday in an office park near Norcross.

Police got a call around 2:30 a.m. "regarding a suspicious person sleeping or possibly dead behind a business" on Technology Parkway South, Gwinnett police Cpl. Edwin Ritter said in a statement. "When officers arrived, they discovered a male deceased with several head injuries from an unknown origin."

Ritter said the man did not have any identification in his possession. He is around 6 feet tall, weighs about 200 pounds and has two tattoos, one of which Ritter said is "very unique in a unique location on the body."

Police were not releasing a description of that tattoo or its location, "in hopes that anyone who is intimately familiar with the male will come forward and help identify this deceased male," Ritter said.

An autopsy was planned to determine how the man died.
