Shocking Twist In Gilgo Beach Case: New DNA Evidence Links Rex Heuermann To Additional Murders

Written by Published

Rex Heuermann, a 60-year-old architect from New York, previously implicated in the murder of four women, has been charged with two additional murders.

The charges come after the discovery of new DNA evidence and a computer document allegedly used by Heuermann to meticulously plan his crimes, according to ABC News.

Heuermann stood before a judge on Long Island's eastern end, facing charges for the murders of Jessica Taylor and Sandra Costilla. Both women, suspected victims of predators targeting sex workers, disappeared in 2003 and 1993 respectively. The charges were filed shortly after police concluded extensive searches of Heuermann's residence in Massapequa Park and a wooded area on Long Island, linked to the notorious Gilgo Beach serial killings.

Prosecutors, in a court filing, revealed that they used advanced forensic testing methods to match hairs found near both victims to a DNA profile that likely belongs to Heuermann. They also found a "planning document" on a hard drive in his basement, which they believe Heuermann used to methodically plan his murders. The document contained Heuermann's worries about leaving forensic evidence, instructions for cleaning and washing bodies, and notes on how to improve his methods for future crimes, as stated in the bail application.

Heuermann pleaded not guilty during the court hearing and was ordered to be held without bail. Suffolk County District Attorney Ray Tierney planned to hold a press conference following the court hearing.

The charges related to Costilla, who was murdered three decades ago, suggest that Heuermann's killing spree may have spanned a much longer period than initially believed. Prosecutors pointed to an entry in the planning documents that implied Heuermann's involvement in the death of another woman, Valerie Mack, whose dismembered body was found near Taylor's. Heuermann has not been charged in Mack's death, who disappeared in 2000.

Since late 2010, police have been investigating the deaths of at least ten individuals, primarily female sex workers, whose remains were found along a secluded highway near Gilgo Beach on Long Island's south shore. The victims vanished over a span of at least 14 years, and the investigation has been marked by slow progress and few leads. Investigators have long suspected that not all the deaths were the work of the same killer. Some victims disappeared as far back as the mid-1990s, and an 11th person who vanished in 2010 from the Oak Beach community was deemed to have accidentally drowned.

Heuermann, who resided across a bay from where the bodies were discovered, was arrested last July. Prosecutors stated that a new investigative task force used mobile phone location data and DNA samples to connect the architect to some of the victims. He was charged with the murders of four women: Megan Waterman, Melissa Barthelemy, Amber Lynn Costello, and Maureen Brainard-Barnes.

Investigators returned to Heuermann's home last month, conducting an extensive search that lasted nearly a week. Their efforts were primarily focused on the basement, according to Heuermanns wife's lawyer. This followed a search in April of a wooded area in Manorville, about 40 miles east of Heuermanns home, linked to another Gilgo Beach victim.

Jessica Taylor, 20, disappeared in 2003 while working as an escort in New York City. Parts of her remains were found in Manorville that year, while others were discovered during a 2011 search of the beach scrub by Ocean Parkway, where other Gilgo Beach victims were found.

In April, investigators also spent several days searching a property in the eastern Long Island hamlet of North Sea, where Costilla's body was discovered in 1993. Costilla was 28 at the time of her death and resided in New York City.

A decade ago, Suffolk County prosecutors publicly stated that they believed Costilla had been killed by a local carpenter, John Bittrolff, who was convicted of murdering two other women found on the same part of Long Island. However, due to insufficient evidence, Bittrolff was never charged with Costilla's death. He maintains his innocence.

Heuermann's lawyer, as well as the lawyers representing his wife and two adult children, declined to comment. Heuermann, who has been in custody since his arrest, pleaded not guilty and is scheduled to return to court on July 30 for a status hearing. No trial date has been set.
