Gwinnett County police have learned the identity of the man found dead last week in an office park.

The body of Ronald Corona, 39, was discovered around 2:30 a.m. Aug. 13 on Technology Parkway South in Peachtree Corners. Police said they received a call about a "suspicious person sleeping or possibly dead" behind a business.

Authorities released photos of the man's tattoos in an effort to find out who he was.

Corona, originally from Pennsylvania, had been living in the Gwinnett area since November, police said.

His cause of death is still undetermined, and the Gwinnett County Medical Examiner's Office is awaiting the results of toxicology tests.
