NEW YORK (CBSNewYork) -- On Long Island investigators hope to be getting closer to finding the serial killer who dumped eight bodies in Suffolk County.
CBS 2's Jennifer McLogan got a closer look at the crime scene on Friday.
With the re-opening of Ocean Parkway, fluorescent orange arrows pointed to locations marking the four newest sets of remains. They may pre-date the four women found wrapped in burlap in December. These chilling finds were unearthed in thick brush, along a mile stretch between Oak Beach and Gilgo Beach.

"We have no information on the sex, or age or any other information on the four remains we found," Suffolk County Police Commissioner Richard Dormer said.
Police told McLogan that with the assistance of the FBI and law enforcement around the country, Suffolk investigators are getting closer to finding the killer -- crediting evidence, clues and anonymous tips.

"All it takes is one phone call -- or an accumulation of a couple of phone calls -- for this thing to get resolved," retired NYPD officer and private investigator Jay Salpeter said.
"We're aware now that we actually do have a serial killer."
Police acknowledged they are re-visiting a possible link between the serial killer and the unsolved murders of four prostitutes in New Jersey in 2006.
"That is certainly part of the investigation," Dormer told WCBS 880's Peter Haskell. "The homicide squad is in contact with Atlantic City Police Department."
One of the New Jersey victims spent time on Long Island -- in a Jericho motel -- before she vanished.
The four prostitutes whose remains were first identified worked as escorts who advertised on Craigslist in various Motels across Nassau County. The first to go missing, Shannan Gilbert, whose cries for help triggered the search last May, has not been found, unnerving local homeowners.
"To find all these bodies here, we're shocked. We are a very close community. We leave our doors unlocked," Oak Beach homeowner Robert LaRosa said.
State police were out all day on Friday. Nassau Police officers on horseback will join them Monday beginning at Tobay Beach. Suffolk Police said they, too, will be back.
Until the killer is caught, Suffolk County Police said residents should be extra careful of any contact made with strangers.
