The Long Island Serial Killer, also known as the Gilgo Beach Killer, is a now identified man, responsible for the murders of multiple people over a period of nearly 20 years, primarily on Long Island, New York. The case gained national attention due to the gruesome nature of the crimes and the long period the killer remained at large.
In December 2010, Suffolk County Police were searching for a missing woman named Shannan Gilbert, a sex worker who had called 911 in distress months earlier. While searching near Gilgo Beach, police found four bodies wrapped in burlap sacks along Ocean Parkway.
In July 2023, a man named Rex Heuermann, an architect from Massapequa Park, was arrested and charged with the murders of at least three women - known as the "Gilgo Four." He is also the prime suspect in a fourth killing.
On June 6, 2024, Heuermann was charged with the murders of Jessica Taylor and Sandra Costilla - the latter not previously linked to the Gilgo Beach case, pushing the timeline back to the early 1990s. In December, he was also indicted for the 2000 murder of Valerie Mack. He has pleaded not guilty to all charges.
As of 2025, the legal process is ongoing, with prosecutors continuing to investigate his possible involvement in other unsolved murders.
I did not know about this killer and this story. I found this documentary interesting and it never felt like it was dragging. The thing that shocked me the most were not the murders themselves, but the checklist and notes Rex Heuermann had on his computer that the police managed to restore. A list of how he could improve his killings and methods, which was absolutely absurd and made me sick to my stomach. Here I will copy and paste a summary of an article I read that covers most of it:
"Accused Gilgo Beach serial killer Rex Heuermann allegedly created disturbing digital checklists that show how he carefully planned and covered up his murders, which he referred to as "hunts," prosecutors revealed. These lists included "pre-prep" and "post event" steps, covering everything from logistics to disposing of evidence. Investigators uncovered these lists while examining a trove of digital devices from his home.
The checklists were organized into:
-Supplies needed.
-Pre-prep tasks (e.g., vehicle inspection, checking for traffic cameras, getting enough sleep).
-Dump site planning.
-Post-disposal actions (e.g., changing tires, preparing an alibi, deleting incriminating files).
Some chilling notes included:
-Get sleep before hunts. Too tired creates problems.
-Use heavy rope... light rope breaks under stress.
-More sleep & noise control = more playtime.
Prosecutors believe "playtime" refers to the torture and bondage of victims. The defense argues these new charges don't align with the original theory, pointing to differences like dismemberment and locations of the new alleged victims."
