"This saga has been the topic of books, multiple documentaries, and consumed online web sleuth and community." — Ashley Flowers
"We have two distinct signatures. The first is the Gilgoboch 4. He thinks they were killed by a, quote, trophy killer, meaning that the way a hunter would put deer heads on his wall, this guy probably lined up all of his victims in an orderly way and he thinks he did it so he could maybe even drive by and see them, like, mounted per say." — Peter (Amateur Profiler, as quoted by Ashley Flowers)
"The eastbound victims and the Gilgo girls were different, but each set of four was exactly the same. Almost like he was just trying something out like a new collection." — Ashley Flowers
The episode begins with an account of Shannon Gilbert's disappearance on May 1st, 2010, after an encounter with a client named Joe and her driver, Michael, in Oak Beach, Long Island. Shannon made a frantic 911 call claiming she was being attacked and later sought help from neighbors before disappearing. Confusion surrounding her location during the 911 call and a suspicious call made by a Dr. Peter Hackett to Shannon's mother added layers of complexity to her case.
The investigation took a significant turn when, in December 2010, a search dog discovered burlap sacks containing skeletal remains on Gilgo Beach. These were identified as four young escorts: Melissa, Megan, Maureen, and Amber, collectively known as the "Gilgo Beach Four." As the investigation broadened, more bodies and body parts were discovered along Ocean Parkway and in Manorville, bringing the total number of victims to at least ten, with varying victim profiles, including a young Asian male and an unidentified infant. This discovery led authorities to suspect a serial killer or multiple killers.
The episode explores the theories of a single serial killer versus two. The "trophy killer" theory posits a killer who meticulously arranged victims, while the "torso killer" theory suggests a perpetrator who dismembered victims and left parts on display. Suspects such as Dr. Hackett, James Besett, and John Bittrol are discussed, along with their potential connections and the evidence against them, though none were definitively identified as the killer(s). The episode highlights the challenges in connecting victims, the potential for law enforcement corruption, and the ongoing mystery surrounding the Long Island Serial Killer(s).
