JONES BEACH - Investigators today swept a 15-mile stretch of the Ocean Parkway on Long Island searching for possible additional evidence or victims after four female bodies were found. Authorities say it could take several weeks before the four bodies are identified.

The Suffolk County medical examiner has determined, however, that none of the bodies were Shannon Gilbert, a Jersey City woman who has been missing since May.

Investigators were searching for Gilbert when they found the remains.
