Suspected Long Island serial killer Rex Heuermann has been charged with two more murders, one of which dates back to 1993.
The Suffolk County District Attorney’s Office announced Thursday that a grand jury has indicted the Massapequa Park, N.Y., architect on two counts of murder in connection with the 1993 deaths of Sandra Costilla and 2003 Jessica Taylor.
Heuermann already faces murder charges in the deaths of Megan Waterman, Melissa Barthelemy, Amber Costello and Maureen Brainard-Barnes. All four women worked as online escorts and disappeared between 2007 and 2010. Their remains were all found in an area on Gilgo Beach in Long Island, NY in December 2010.
Taylor’s remains were discovered on July 26, 2003, by a witness walking their dog, according to an amended criminal complaint, which states she was “laying on her back with her legs bent under her.”
A tattoo on her torso had been “severely obliterated by a sharp object” and her arms had been decapitated, according to the indictment released Thursday.
Costilla’s remains were discovered on Nov. 20, 1993, by two people who were hunting in a wooded area and she was found “lying on her back with her arms extended above her head with her uncovered legs apart,” according to the indictment. Costilla, who was from Trinidad and Tobago, had several “sharp force injuries” across her body.
Bob Macedonio, the attorney for Asa Ellerup, Heuermann’s wife, told PEOPLE that the Suffolk County District Attorney’s Office and other law enforcement personnel searched Heuermann’s home for six days last month.

According to Macedonio, the search focused mainly on the basement.
Heuermann – a father of two – was arrested on July 13, 2023 near his office building in Manhattan.
Heuermann was reportedly linked to the murders of Waterman, Barthelemy, Brainard-Barnes and Waterman through burner phones and DNA evidence found on the victims.

He was also traced to a Chevrolet Avalanche registered to him that was reportedly seen at the time of Costello’s disappearance. Authorities also found evidence that Heuermann was allegedly obsessed with the case and searched for articles about the task force created to investigate the murders.
According to authorities, his searches included: “Why couldn’t police trace the Long Island serial killer’s phone calls” and “why hasn’t the Long Island serial killer been caught.”
