The Long Island Serial Killer (also referred to by media sources as the "Gilgo Killer") is an unidentified suspected serial killer who is believed to have murdered 10 people associated with the sex trade over the last 15 or so years and dumped their bodies along the Ocean Parkway, near the remote beach towns of Gilgo Beach and Oak Beach in Suffolk County and the area of Jones Beach State Park in Nassau County.The remains of four victims were found in December 2010, while six more sets of remains were found in March and April 2011. Police believe that the latest sets of remains predate the four bodies found in December 2010.
On May 9, 2011, authorities surmised that two of the newest sets of remains might be the work of a second killer. On November 29, 2011, however, the police announced that they believe that one person is responsible for all 10 deaths and that they do not believe that the case of Shannan Gilbert (see below) is related.According to Suffolk County District Attorney Thomas Spota, "It is clear that the area in and around Gilgo Beach has been used to discard human remains for some period of time."
