The 20-year search for Valerie Mack is finally over.

The 24-year old woman, who was last seen by her family around Port Republic in the spring or summer of 2000, is believed to have been a victim of a Long Island, NY, area serial killer. For years, she had been "Jane Doe No. 6" in the investigation.

Authorities say Mack was working as an escort in Philadelphia at the time of her disappearance. She also went by the name of Melissa Taylor.

Mack's partial remains were found in a wooded area off a Long Island highway the same year she went missing, and more than a decade later, her dismembered remains were found along Ocean Parkway.

The police department worked with the FBI using DNA techniques to identify Mack.

ABC 6 TV New York reports that Suffolk County Police Commissioner Geraldine Hart made this statement concerning mack's identification.

"For two decades, Valerie Mack's family and friends were left searching for answers and while this is not the outcome they wanted, we hope this brings some sense of peace and closure. "I would like to thank the FBI for its continued support and partnership in the Gilgo Beach homicide investigation and for their assistance utilizing scientific techniques that has moved this case forward. We will continue to use every investigative tool available to aggressively investigate these murders."

Police are still searching for the person who killed 11 people whose remains were found at the Long island beach known as Gilgo Beach.
