Suspected Gilgo Beach Serial Killer Rex Heuermann Charged in Deaths of Two More Women, Expanding Timeline by Nearly Two Decades

Rex Heuermann, a New York architect and suspected serial killer, has been charged with the murders of two more women: Jessica Taylor and Sandra Costilla. The new charges expand the timeline of Heuermann's alleged crimes by nearly two decades.

Jessica Taylor's partial remains were found near Gilgo Beach in 2011 and linked to other remains from 2003. Her body was discovered in a wooded area of Manorville, farther east on Long Island. Sandra Costilla's remains were found in North Sea, in the town of Southampton, and she was killed in 1993.

Heuermann is believed to have mutilated the victims to inhibit identification via facial recognition, fingerprints and/or tattoo identification. DNA from a male human hair recovered from Taylor's body linked Heuermann to her death. Phone records showed that Heuermann's wife and children were out of town at the time of Taylor's killing.

The investigation into the Gilgo Beach murders dates back to late 2010, when investigators discovered the first of ten victims along a desolate stretch of Ocean Parkway running east from Jones Beach. The latest charges against Heuermann follow a recent flurry of activity in the investigation, including a nine-day canine search completed last month in Manorville and Southampton and six-day search of his home in Massapequa Park.

Heuermann has been charged with the murders of four women: Shannan Gilbert, Megan Waterman, Melissa Barthelemy, and Amber Costello. He pleaded not guilty to all charges in connection with their deaths and remains in jail awaiting trial.

The Gilgo Beach investigation is ongoing.

    • Sandra Costilla's body was found with a hair match to a witness who lived at Heuermann’s residence. She went missing around November 1993 and was found in Southampton.
    • Jessica Taylor's remains were discovered near Mill Road in July 2003 and again in March 2011.
    • Investigators found over 350 electronic devices at Heuermann’s residence containing a significant collection of violent pornography dating back to 1994.
    • A Word Document dated back to the year 2000 was discovered, which appears to be Heuermann’s planning document with columns for ‘PROBLEMS’, ‘SUPPLIES’, and a ‘DS’ column listing Mill Road as a possible dumpster site.
  • Deception (30%)
    The article contains selective reporting as it only reports details that support the author's position and implies facts without linking to peer-reviewed studies which have not been retracted. The document found on Heuermann's hard drive is referred to as a 'planning document' used to 'blueprint' his crimes, but no evidence is provided that this document was created by Heuermann or that it was used in the commission of any crimes. Additionally, the article makes emotional appeals by describing the victims as young women who were long suspected of being victims of men preying on sex workers.
    • It also has a place to note practical lessons for ‘next time.’
    • Heuermann pleaded not guilty at the court hearing and was ordered held without bail.
    • The new charges came just days after police finished extensive searches of Heuermann’s Massapequa Park home and a wooded area on Long Island tied to the investigation of a string of deaths known as the Gilgo Beach serial killings.
  • Fallacies (90%)
    The article contains an appeal to authority fallacy when it states that 'prosecutors say they discovered a 'planning document' on the hard drive found in his basement used to 'methodically blueprint' his killings.' This statement implies that the document is definitive evidence of Heuermann's guilt, but it does not provide any information about how reliable or valid this evidence is. Additionally, there are several instances of inflammatory rhetoric used throughout the article, such as 'New York architect previously accused of killing four women and leaving their corpses scattered along a coastal highway' and 'The new charges came just days after police finished extensive searches of Heuermann’s Massapequa Park home and a wooded area on Long Island tied to the investigation of a string of deaths known as the Gilgo Beach serial killings.' These statements are not necessary for understanding the facts of the case and serve only to inflame emotions.

  • Fallacies (95%)
    The article contains some inflammatory rhetoric and an appeal to authority fallacy, but no formal logical fallacies were found. The inflammatory rhetoric includes phrases like 'hunt too long seen in area too long' and 'more sleep and noise control would allow for more play time', which could be interpreted as sensational or provocative. The appeal to authority fallacy is present when the author states that some notes from the document were sourced from a book, implying that the information in the book is trustworthy because it was used as a source. However, this does not necessarily mean that the information in the article itself is true or accurate.
