The search for a young woman whose car was found at Caumsett State Park will resume Sunday morning, Nassau County police said.

The park, located in Huntington Town on Long Island Sound, was closed for much of Saturday as authorities looked for the unidentified woman.

A police spokeswoman said a missing-person report was filed Friday for a 22-year-old Great Neck woman. She could not immediately confirm whether the woman in the report was the subject of the Caumsett search.

A spokesman for the New York State Office of Parks, Recreation and Historic Preservation was not available to say when the park would reopen to the public.

The stable is expected to open Sunday morning so that people can take care of their horses, but the rest of the park will remain closed.

Caumsett is popular with runners, bicyclists and equestrians. A notice to those who use the stables noted that the park was closed for a police investigation.

On Saturday afternoon, the missing woman’s car, a white Honda Accord, remained in the parking lot, surrounded by police cones.

State Park Police, Department of Environmental Conservation officers, and Suffolk police officers, aided by their dogs, assisted in the search, along with Nassau air and marine officers.

The Huntington First Aid Squad and the Huntington and Cold Spring fire departments also were on the scene.

The woman’s car first was spotted at the park on Thursday, but could have been there earlier, officials said.
