(CBS/WCBS/AP) NEW YORK - Police may have a suspect in their sights in the case of the possible Long Island serial killer and it could be one of their own.

According to ABC News, police have been troubled by the lack of clues, despite an extensive number of crime scenes to investigate, and some suspect the killer may be familiar with police procedures.

"[The killer] could be law enforcement, could be a civil servant, could be a code enforcement person, could be a building inspector, could be a postman ... or it could be anyone who knows the area quite well," former New York Police Department detective Wally Zeins told ABC News.

Authorities are expanding their search for more possible victims into Nassau County Monday.

Police told CBS affiliate WCBS they were getting closer to finding the killer, but declined to provide further details.

Police planned to expand their search Monday to nearby Tobay Beach. Jones Beach is also a possible search site. The expanded search comes after investigators recovered eight bodies on Suffolk County beaches. None of the four most recently recovered bodies have been identified.

"We have no information on the sex, or age or any other information on the four remains we found," Suffolk Police Commissioner Richard Dormer told WCBS.

Police, however, have ruled out that the remains are those of 24-year-old Shannan Gilbert of Jersey City, a reputed prostitute. She disappeared May 1 after running from a client's house in Oak Beach.

The initial search for Gilbert back in December led police to the bodies of four women wrapped in burlap, unburied in the thick brush.

All four worked as escorts who advertised on Craigslist and worked in various Nassau hotels.

"Either he knows what he's doing and understands what crime scene investigation is all about or he has just been lucky up until now," said Lawrence Kobilinsky, professor of John Jay College of Criminal Justice.
