Authorities believe that Heuermann, a 61-year-old former architect and father, had been active as a serial killer since the early 1990s. During the extensive investigation, police seized hundreds of electronic devices from his home.
Prosecutors pointed to a “planning document” found on a hard drive in Heuermann’s basement, which allegedly served as a blueprint for the murders.
Latest Charges and Key Evidence
The latest charge stems from the death of Valerie Mack.
Suffolk County District Attorney Ray Tierney emphasized the importance of seeking justice for the victims and their families, stating at a news conference, “The lives of these women matter. No one understands that more than the families.”
Mack’s skeletal remains were initially discovered in Manorville, New York, in 2000.
Over a decade later, additional remains were found near Gilgo Beach.
Genetic testing in 2020 officially identified the remains as Mack’s. Prosecutors noted that a human hair found on her remains likely belonged to Heuermann’s daughter, who was just 3 or 4 years old at the time of Mack’s death. Authorities clarified that the daughter is not accused of any knowledge of the crime or wrongdoing of any kind.
