WANTAGH, N.Y. -- Police are returning to a barrier island of Long Island to focus on an area where the most recent human bones were found.

A wildlife sanctuary near Tobay Beach will be searched on Friday. A human skull was found there on April 4. And human bones also were found nearby along Ocean Parkway.

They are among 10 sets of remains found near the parkway.

The first four were found in December. Remains were found in six other locations in recent weeks, although they have not officially been linked to those found in December.

The first remains were found during an investigation into the disappearance of a New Jersey prostitute last seen in Oak Beach a year ago. She hasn't been found.
