DACULA, Ga. -- Human remains were found in some woods near Dacula, police said.

Gwinnett County police said in a statement Tuesday that the remains were found on Monday near the intersection of Drowning Creek and Tanner roads in unincorporated Gwinnett County.

The remains were found by workers of a tree cutting company, investigators said.

The medical examiner said the remains were at least a year old. The gender and cause of death have not yet been determined, police said.

According to the statement, a preliminary review of dental records by the medical examiner likely ruled out that the remains are those of Justin Gaines, a teenager who disappeared in November 2007.
