(NEW YORK) -- Authorities in Suffolk County, New York, on Tuesday released video evidence from the unsolved Gilgo Beach murders, showing the last known surveillance of Megan Waterman, one of the victims.
Suffolk County Police also announced it is doubling the Crime Stoppers reward to $50,000 for information that leads to an arrest and conviction in the case.
Waterman, whose remains were found along Ocean Parkway, near Gilgo Beach in 2010, was last seen at Holiday Inn Express in Hauppauge, New York, in June 2010. She had advertised escort services on Craigslist.
The remains of 10 people were found in 2010 and 2011 in the weedy sections off Ocean Parkway near Jones Beach. At the time, police said half of the identified victims worked as prostitutes.
Earlier this year, Suffolk County Police Commissioner Rodney K. Harrison created the Gilgo Beach Homicide Investigation Task Force. The task force includes representatives from the FBI, New York State Police, the Suffolk County District Attorney's office and the Suffolk County Sheriff's Office.
In 2020, police released photos of a belt believed to be handled by the suspect, which did not belong to any of the victims, hoping to advance the investigation.
Authorities discovered the remains during the search for Shannan Gilbert, a sex worker from New Jersey, but she is not believed to be tied to the other deaths because she did not match the pattern of the Gilgo Beach homicides, police said in 2020.
Remains found on Dec. 11, 2010 during the search for Gilbert, were later identified as the remains of 24-year-old Melissa Barthelemy. Two days later, three more victims were found on Ocean Parkway. They were later identified as Maureen Brainard-Barnes, 25; Amber Lynn Costello, 27; and Megan Waterman, 22.
All four women worked as Craigslist escorts.
The remains of another woman who worked as an escort were found on March 29, 2011, but the remains have not been identified.
On April 4, 2011, three more sets of remains were found on Ocean Parkway, which were those of a toddler, an unidentified Asian male and a third victim who was later identified as Valerie Mack.
Two more sets of remains were found a week later, one of which was discovered to be the mother of the toddler. The mother's partial remains were first found in 1997.
Gilbert's remains were found in December 2011.
