MANLIUS, N.Y. -- The body of a woman was pulled from a lake Saturday afternoon at Green Lakes State Park.

A visitor called 911 when she saw what looked like a body floating in Green Lake at the park, off Green lake Road in the town of Manlius.

The body of the woman was pulled from the water by the Fayetteville Fire Department just after 1 p.m. Trooper Jack Keller, a New York State Police spokesman, said troopers and the New York State Park Police were working to identify the woman.

Police kept the area blocked off all day. Investigators came and went, and state police divers arrived at the scene.

Crowds turned out to the park Saturday to enjoy the mild weather and fall foliage. People who went for a walk or run around Green Lake were turned away when they reached the crime scene tape.Many left wondering aloud about what had happened.

A TLC Ambulance crew rolled a body on a gurney away around 6 p.m. The Onondaga County Medical Examiner's Office will conduct an autopsy to determine how the woman died, Keller said.
