After nearly two decades, police in Long Island have identified the Long Island serial killer’s sixth victim, known until now as Jane Doe #6, using genetic genealogy technology (DNA). The victim was Valerie Mack.

Mack went missing in 2000. She was 24 years old and worked as an escort in Philadelphia. Her partial remains were found that same year in a wooded area off Halsey-Manor Road in Manorville. A year later, her dismembered remains were found along Ocean Parkway in Gilgo Beach.

In 2011, an analysis of DNA confirmed that additional remains found along Ocean Parkway belonged to a previously discovered person known as Manorville Jane Doe #6. With new DNA technology and help from the FBI’s LIRA Office in Melville, detectives were able to get more leads to investigate. They went to parts of New Jersey where they thought Manorville Jane Doe might have had connections. They talked to possible relatives and got more DNA samples to test. After comparing the new DNA with that of Manorville Jane Doe, they confirmed that the remains were actually those of Valerie Mack, who was born on July 2, 1976 and last lived in the Philadelphia, Pennsylvania area.

Valerie Mack was a 24-year-old white female who worked as an escort in the Philadelphia, Pennsylvania area under the name Melissa Taylor. Although she was never listed as a missing person, Valerie was last seen by her family members in the Spring/Summer of 2000 near Port Republic, New Jersey.
