Who were Rex Heuermann's victims? Gilgo Beach suspect charged with murder of 7th woman
Suspected Gilgo Beach serial killer Rex Heuermann has been charged with the murder of a seventh victim, Valerie Mack.
Suspected Gilgo Beach serial killer Rex Heuermann has been charged with the murder of a seventh victim. The new superseding indictment was released in Suffolk County court on Tuesday, December 17.

Heuermann, 60, has been charged with second-degree murder in the killing of Valerie Mack. The victim’s partial remains were found on Long Island in New York in November 2000. Shaking his head no, Heuermann said in court on Tuesday, according to CNN, “Your honor, I am not guilty of any of these charges.”
Mack, a 24-year-old Philadelphia mother, used to work as an escort when she disappeared. “The Mack family is emblematic of the other families in this case, who have steadfast stood by their loved ones and zealously guarded their memories,” Suffolk County District Attorney Raymond Tierney said in a news conference following the court appearance.

Heuermann’s attorney, Michael Brown, said his client was surprised by the latest charge and is “adamant that he did not do these crimes.” The next hearing has been scheduled for January 15.
A group of hunters with a dog found parts of Mack’s remains in a wooded area of Manorville. The hunters subsequently called 911. Human hair found on Mack’s left wrist went on to lead prosecutors to the DNA profiles of Heuermann’s wife Asa Ellerup, and daughter Victoria Heuermann. According to two forensic laboratories, hairs recovered on six of the seven alleged victims are “forensically tied” to Heuermann or members of his immediate family, or other people he lived with, a legal filing has said.
Mack’s head, hands, and right foot remained missing for about 11 years after the initial investigation in Manorville in 2000. Her skull, hands, and right foot were found east of Gilgo Beach in Suffolk County in April 2011. These remains were found less than 1.5 miles east of where the remains of Heuermann’s alleged victim Jessica Taylor.
