Serial-Killer Architect Facing New Charges in Long Island Murder Case – Shocking Details Revealed

RIVERHEAD, N.Y. (AP) — A New York architect has been newly charged with the deaths of two young women, Jessica Taylor and Sandra Costilla, in addition to the four women he was previously accused of killing. Rex Heuermann, 60, appeared in court on Long Island to face these charges after new DNA evidence was gathered, and a computer document was found detailing the planning of his crimes.

Prosecutors revealed that forensic testing matched hairs found near the victims to a DNA profile likely belonging to Heuermann. The discovered document found on his hard drive laid out a methodical plan for the killings, including instructions on body preparation and notes on lessons learned from previous crimes.

Heuermann, who pleaded not guilty, was ordered to be held without bail following his court appearance. Suffolk County District Attorney Ray Tierney planned to hold a news conference to discuss the case further.

The newly added charges indicate that Heuermann may have been involved in the deaths of more victims, including Valerie Mack, who disappeared in 2000. The investigation into these serial killings has been ongoing since late 2010 and has revealed the deaths of at least 10 people, primarily female sex workers, along a desolate highway near Gilgo Beach on Long Island’s southern shore.

Heuermann was arrested last year after mobile phone data and DNA samples pointed to him as the perpetrator of the murders. He was initially charged with killing Megan Waterman, Melissa Barthelemy, Amber Lynn Costello, and Maureen Brainard-Barnes. Investigators have conducted multiple searches of Heuermann’s residence, including his home in Massapequa Park and a wooded area in Manorville, linked to one of the victims.

The ongoing investigation has brought new details to light, such as references in Heuermann’s document to books by retired FBI agent John Douglas on the psychology of serial killers. As the case unfolds, prosecutors and investigators work to bring justice for the victims and their families.
