Atlanta Police Maj. Keith Meadows said investigators with the Fulton County Medical Examiner's office were able to identify Myrick from medical records.
The medical examiner's Web site described the body as weighing about 110 pounds with surgical scarring on her left ankle and evidence on her left leg of "surgical placement of plates and screws."
Myrick, whom police said lived in DeKalb County, wasn't listed in Atlanta police missing person's database.
Investigators aren't sure what happened in the moments leading up to her death, but Meadows said detectives are placing her final hours sometime between late Saturday night and early Sunday morning.
"We have not been able to retrace her steps," he said.
Police said there were no other initial signs of injury or sexual assault, but the full autopsy report from the medical examiner's office is still pending.
Meadows said Myrick is believed to be a mother of three adult-aged children, and was known to frequent a notorious section of Moreland Avenue and Memorial Drive in DeKalb County. Police are canvassing the area and talking with Myrick's family.
"We are seeking to question some of Ms. Myrick's known associates," Meadows said. "At this point we have not developed or eliminated one particular person as a suspect."
Authorities said Myrick has had some minor criminal activity in her past, including a Fulton County probation violation arrest in February 2009 for a previous criminal trespassing charge.
