CUMMING — Results from an autopsy on the body of a man that was found Monday morning on the Lake Lanier shoreline at Mary Alice Park are expected Wednesday, authorities said.

Park visitors apparently saw the body as they were walking along the beach, according to the Forsyth County Sheriff’s Office.

The Georgia Bureau of Investigation planned to perform the autopsy Tuesday afternoon, said Doug Rainwater, a spokesman for the agency, while investigators continue to pursue the man’s identity. The GBI will attempt to get a fingerprint from the body.

No one has come forward in reference to the man or a missing family member, which Rainwater said is unusual in such a case.

Forsyth County does not have any open missing person reports, but neighboring Gwinnett County has 20 such cases and Hall County has four, according to Rainwater.

They will all be looked into as part of the investigation once the age range is determined in the autopsy.

The sheriff’s office and the Forsyth County Fire Department were at the park Monday to gather more information before and after the sheriff’s marine patrol unit removed the body from the lake.

Due to the length of time it had been in the water, no identifying features were immediately distinguishable, authorities said.

The park remained closed while the investigation continued, but has since been reopened.

It was not immediately clear if foul play is suspected.
