Rex Heuermann, the Long Island Serial Killer suspect, has been charged with two additional murders, including one dating back to 1993.
The Suffolk County District Attorney’s Office announced Thursday that a grand jury indicted Heuermann, an architect from Massapequa Park, N.Y., on two counts of murder for the deaths of Sandra Costilla in 1993 and Jessica Taylor in 2003.
Heuermann is already facing murder charges for the deaths of Megan Waterman, Melissa Barthelemy, Amber Costello, and Maureen Brainard-Barnes.
These four women, who worked as online escorts, disappeared between 2007 and 2010. Their remains were discovered in December 2010 in an area on Gilgo Beach in Long Island, N.Y.
According to an amended indictment, Taylor’s partial remains were found by a witness walking their dog on July 26, 2003. She was discovered “lying on her back with her legs bent underneath her,” with a tattoo on her torso “severely obliterated by a sharp object” and her arms cut off. Additional remains, including her skull, were found in 2011.
Costilla’s remains were discovered on November 20, 1993, by two hunters in a wooded area. She was found “lying on her back with her arms outstretched over her head and her uncovered legs spread apart,” bearing several “sharp force injuries” across her body. Costilla was from Trinidad and Tobago.
The indictment also describes a planning document investigators found, which allegedly details Heuermann’s meticulous preparations.
The document includes columns labeled “Problems,” “Supplies,” “DS,” and “TRG.”
The “Problems” column lists concerns such as “hair & fiber,” “DNA,” “finger prints in gloves,” and “blood stains.”
The “Supplies” list includes items like “saw / cutting tools,” “lie / acid,” “burn can,” and a police scanner.
The “TRG” column notes “small is good,” which investigators believe refers to Heuermann’s preference for petite victims.
In a section titled “Things to Remember,” Heuermann allegedly wrote notes such as “get sleep before hunt too tired creates problems” and “hit harder too many hit to take down, consider hitting neck next time for take down.”
Bob Macedonio, attorney for Asa Ellerup, Heuermann’s wife, said that law enforcement searched Heuermann’s house extensively last month, focusing on the basement.
Heuermann, a father of two, was arrested on July 13, 2023, near his Manhattan office.
He was allegedly linked to the murders of Waterman, Barthelemy, Brainard-Barnes, and Costello through burner phones and DNA evidence found on the victims.
A Chevrolet Avalanche registered to him was reportedly seen at the time of Costello’s disappearance.
Authorities also found evidence of Heuermann’s obsession with the case, including searches about why the Long Island serial killer hadn’t been caught and why law enforcement couldn’t trace the calls made by the killer.
Investigators also found hundreds of internet searches related to raping and torturing women, child sexual abuse material, and searches for information on his alleged victims and their families.
