The Gilgo Beach Killer

"The Gilgo Beach Killer" is a recent and profilic still-unidentified serial killer who is believed to have killed several people in a period of nearly 20 years.

Brief Case History
The police investigation originally centralized on the search for Shannan Gilbert, an escort from New Jersey, who was reported missing in May 2010. She was last seen in the area after she ran from, rather than to, her driver, Michael Pak. Before going missing, Gilbert managed to make a 911 phone call, panicking and saying that "they were going to kill her". In December, a police officer was exercising with his dog when he accidently found the skeletal remains of a woman in a nearly disintegrated burlap sack. Following this discovery, three more bodies were found two days later, in the same area on the north side of the Ocean Parkway. The bodies led police to believe that a serial killer was responsible. The investigation was expanded to Nassau County, where they eventually found more remains. On June 16, Suffolk County police raised the reward from $5,000 to $25,000 for information about the killer or the victims, the largest ever offered in the county's history. On November 29, police announced that they believe one killer is responsible for all the murders and that the person is almost certainly from Long Island. On December 13, the remains of Shannan Gilbert were found in a marsh about half a mile from where she disappeared, some of her clothes were also found a week later. Speculations suggested that serial killer Joel Rifkin was responsible for some of the older remains, but he denied any involvement with the case. As of today, the identity of the killer, currently known as Unsub, is uncertain.

Modus Operandi
Most of The Gilgo Beach Killer's victims were women associated with sex trade, though his method of murder is currently unknown, he placed their bodies inside burlap sacks and dumped them along the Ocean Parkway, near the remote Long Island towns of Gilgo Beach and Oak Beach.

Profile
It has been suggested that the serial killer is most likely a white male in his mid-20s to mid-40s who is very familiar with the South Shore of Long Island and who has access to burlap sacks which he uses to contain the bodies in. He may have a detailed knowledge of law enforcement techniques and perhaps even ties to law enforcement which have thus far helped him avoid detection.

On Criminal Minds
Though the case didn't become infamous until a few months after Remembrance of Things Past aired, Lee Mullens's habit of having his victims call their families has some similarity to an incident involving The Gilgo Beach Killer. A few weeks after one of his victims disappeared, he is believed to have used her cell phone to call her sister and taunt her.
