‘Torture marks, play time’: Alleged Gilgo Beach serial killer’s sick secret notes

WARNING: distressing content

Accused Gilgo Beach serial killer Rex Heuermann kept a stomach-churning “planning document” that outlined his grisly murders — which also included a chilling “Things to Remember” section and a morbid “Lessons Learned” section , officials revealed.

An “allocated space” computer file that Heuermann allegedly attempted to delete drew a gruesome map of the savage murders of six prostitutes dating back to 1993, including the beheading and mutilation of two victims newly linked to the hulking Long Island, Suffolk dad. County prosecutors said Thursday.

In one disturbing note, Mr. Heuermann — a New York City architect and married father of two — allegedly indicated that he intended to continue killing, prosecutors said.

“Members of the Gilgo Homicide Task Force believe these references to ‘next time’ indicate Heuermann’s prior experience and what changes to implement moving forward,” the DA’s document states.

The revelation came as the district attorney’s office hit Mr. Heuermann with new charges related to the 1993 murder and mutilation of Sandra Costilla and the 2003 beheading and dismemberment of Jessica Taylor — on top of the pending criminal charges he already faced for the death of the women known as the “Gilgo Quattro”.

According to a bail application filed by prosecutors on Thursday, Mr. Heuermann had kept a secret digital log titled “HK2002-2004” on his computer since at least 2000, keeping precise notes about the murders.

The digital document was divided into specific sections such as “Issues,” “Supplies,” “TGR,” which prosecutors say could be potential targets, and “DS,” presumably for “landfill.”

The patient instruction file notes that “small is good” for potential victims and includes a three-part section for “Pre-Prep,” “Prep” and “Post-Event,” the DA’s court document says of Suffolk.

“Hong Kong’s planning document continues to further explain preparatory measures, such as specific ‘reconnaissance’ measures taken”, including “packaging [a body] for transport,” the investigators said.

One section, titled “Body Preparation,” involves “removing the head and hands,” which the DA’s office says is consistent with the remains of Ms. Taylor and another Gilgo body, Valerie Mack, who did not was officially linked to Mr. Heuermann.

The section reminds the accused killer to “remove identifying marks [tatoos] [sic]”, which is consistent with Ms. Taylor’s remains, which featured “linear lesions,” particularly “around where Ms. Taylor’s tattoo was located, which investigators believe was intended to inhibit identification.” of the victim.

Another bullet point reads: “Remove signs from tourture [sic].”

Finally, Mr. Heuermann would keep a “Things to Remember” section, which contained convoluted reminders such as “hit harder” for “next time” and use a heavier rope because “the light rope broke under [stress of being tightened]”.

“Hit harder, too many hits to knock out,” the planning document says, according to prosecutors.

“Consider a shot to the face or neck next time for the takedown.”

Additionally, Heuermann advocates the importance of sleep to avoid “problems” and increase what he calls “play time,” prosecutors said.

Ms Costilla was initially believed to be linked to convicted serial killer John Bittrolff, but documents filed by prosecutors on Thursday said her DNA did not match his.

Who were the victims of Gilgo Beach?

Alleged serial killer Rex Heuermann was arrested last July in connection with the long-unsolved Gilgo Beach murders.

The arrest is linked to the so-called “Gilgo Four,” women found wrapped in burlap within days of each other in late 2010.

Gilgo Beach is located about an hour southeast of New York City.

The years-long investigation that led to the arrest revolved around the discovery of more than 10 sets of human remains along Ocean Parkway near Gilgo Beach in Suffolk County between December 2010 and April 2011.

Most of the victims were small sex workers with green or hazel eyes. But there were also two exceptions: a two-year-old girl and a young Asian man.

• Melissa Barthelemy, 24 years old

Mrs. Barthelemy was a prostitute who lived in the Unionport area of ​​the Bronx and dreamed of one day opening her own beauty salon. She was last seen alive in her basement apartment on Underhill Avenue on July 12, 2009. Mr. Heuermann was charged with Ms. Barthelemy’s murder in July 2023.

• Maureen Brainard-Barnes, 25

Mrs. Brainard-Barnes lived in Norwich, Connecticut. She disappeared after taking an Amtrak train from New London, Connecticut, to Grand Central Terminal in Manhattan on July 6, 2007.

• Megan Waterman, 22 years old

Ms. Waterman, 22, a mother of one, was last seen on June 6, 2010. She lived in Scarborough, Maine, and earned her living as an escort.

Mr Heuermann was charged with Ms Waterman’s murder in July 2023.

• Jessica Taylor, 20 years old

Remains belonging to Ms. Taylor, a 20-year-old woman who worked as an escort in New York City, were found in a wooded area in Manorville on July 26, 2003. Her additional remains – initially labeled “Jane Doe No. 5” – they were discovered on March 29, 2011, along Ocean Parkway.

• Valerie Mack, 24 years old

Ms. Mack was 24 years old and living in Philadelphia when she disappeared. She worked as an escort, using the alias “Melissa Taylor”. Her relatives last saw Ms. Mack in the spring or summer of 2000 in Port Republic, New Jersey, but her disappearance was never reported to the police. Her partial skeletal remains were found in Manorville in September 2000, but were initially known as “Jane Doe No. 6.” More bones were found April 4, 2011, along Ocean Parkway.

• Unidentified Asian man

The skeletal remains of a yet-to-be-identified Asian man were found along Ocean Parkway on April 4, 2011. The man was estimated to be between 17 and 23 years old at the time of his death. He was about five feet six inches (168 centimeters) tall with ugly teeth.

• ‘Peaches’ and her daughter

The partial remains of an African-American woman were discovered in Hempstead Lake State Park in 1997, and she had become known as “Peaches” because of the tattoo of a bitten peach on her left breast. On April 4, 2011, police discovered the remains of a little girl, who was approximately two years old at the time of her death. DNA testing confirmed that one of the skeletons was that of the two-year-old girl’s mother, “Peaches.”

• Karen Vergata

A victim previously referred to as “Jane Doe No. 7” was identified as Ms. Vergata, a 34-year-old Manhattan woman. Ms. Vergata is believed to have disappeared on or about February 14, 1996. Two months later, her legs were found in a plastic bag in a park near Fire Island’s Blue Point Beach. It is believed that at the time of her disappearance Vergata was working as an escort. Two groups of Vergata remains were identified in August 2023.

• Shannan Gilbert, 23

Ms. Gilbert was a Craigslist escort living in Jersey City. She traveled with her driver Michael Pak from Manhattan to meet a client, Joseph Brewer, at her home in the Oak Beach Association on the morning of May 1, 2010. She spoke to two neighbors before disappearing. Her body was discovered in a marsh near Oak Beach, about half a mile from where she was last seen alive on Dec. 13, 2011.

• Sandra Costilla

Ms. Costilla was murdered in 1993 but until now had not been included among the so-called Gilgo Beach victims. Investigators suspected convicted serial killer John Bittrolff in Ms. Costilla’s death, but he was never charged with her murder, which remains one of several unsolved murders on Long Island.
