5 Key Facts Netflix’s Gone Girls Documentary Misses About the True Long Island Serial Killer Case

This article delves into the sensitive topic of several murders tied to the Long Island Serial Killer case, which has also been linked to instances of sexual assault.

As of now, Rex Heuermann, the key suspect in these murders, has yet to face trial, thereby maintaining his presumption of innocence under the legal framework.

In the realm of true crime, Netflix’s documentary series Gone Girls: The Long Island Serial Killer examines the chilling events surrounding these murders in the Gilgo Beach area. Notably, the documentary omits several significant facets of the ongoing investigation. The quest for Shannan Gilbert unearthed numerous bodies in close proximity to Gilgo Beach, indicating the existence of a serial killer. The documentary culminates with the suspect being charged, but with his trial pending, many details remain undisclosed.

The true crime genre is experiencing a surge in popularity, and Gone Girls has garnered favorable reviews for its captivating take on this lesser-known case. Nevertheless, as the suspect has not yet been convicted, the unfolding real-life saga suggests that many unanswered questions linger, hinting at potential updates that could emerge as the case continues. While the documentary concentrates primarily on “The Gilgo Four,” it overlooks critical elements that could provide deeper insights into the Long Island Serial Killer case.

The investigation into the Long Island Serial Killer case remains active, and the documentary aired amidst ongoing evidence collection. An addendum at the conclusion of Gone Girls disclosed crucial updates, including charges against Rex Heuermann for seven murders. The latest victim to be identified is Valerie Mack, previously known as Jane Doe No. 6.

Similar to many of the other victims discovered in the area, Valerie Mack was employed in sex work. Thanks to advancements in forensic DNA analysis, her identity was established, revealing that she was just 24 years old and had prior legal issues related to her work. Her partial remains were located in 2010 and 2011; however, the documentary concluded before Valerie’s identification was finalized, leading to the inclusion of an addendum.

A Possible Disturbing Theory

Shannan’s Phone Call Suggested Possible Accomplices

As Rex Heuermann prepares to stand trial, his interactions with the alleged victims will undoubtedly come under scrutiny. One particularly alarming encounter, which was excluded from Gone Girls but featured in the dramatized film Lost Girls, raises significant questions. Initially, Lost Girls portrayed the murders without a defined suspect, hinting at the possibility that the assailant may not have acted alone.

The contents of Shannan Gilbert’s ominous 911 call have drawn attention, showcasing her distress when she reported to the operator that “they”were trying to kill her. This supports the theory introduced in Lost Girls and prompts a chilling inquiry: who else remains at large? Though she appeared to be in the company of friends, it’s unclear whether she was alluding to a stranger present or another potential accomplice, a theory that Netflix’s Gone Girls did not explore.

Most confirmed victims of the Long Island Serial Killer were sex workers, predominantly female and aged in their 20s. However, there exist a few notable exceptions. One such case, dating back to 2011, remains unresolved, with the individual believed to have been deceased for approximately five to ten years. Gone Girls primarily centered on Shannan and the Gilgo Four, neglecting to delve into the implications of this unidentified individual, whose characteristics may link Rex’s internet history to these heinous acts.

Among various concerning online inquiries related to sadism and women, Rex Heuermann’s searches also included young Asian men. The unidentified victim matches this description, colloquially referred to as “Asian Doe.”This individual, believed to be Asian, male, and young, was found dressed in women’s clothing. Law enforcement remains uncertain if this attire was imposed by the killer or if the individual was indeed a trans woman, leading them to release forensic sketches presenting both long and short hairstyles.

Two particularly heart-wrenching cases highlighted in the documentary involve a woman referred to as “Peaches”and her young daughter. The nickname stems from a peach tattoo that she bore. Nearby, the remains of a toddler called Baby Doe were also exhumed, eventually revealing a tragic connection as Peaches’ daughter.

To identify Peaches, law enforcement distributed images of her tattoo through tattoo magazines, seeking assistance from those who may have known her artist. They eventually connected with the tattooist, who recounted memories of Peaches as a young Black woman accompanied by her female relatives. Although Peaches remains unidentified, the efforts by law enforcement showcase an admirable commitment to uncovering the truth—details that warranted further exploration in the documentary.

Mari Gilbert’s Tragic Death

Mari Was Killed by One of Her Daughters

The conclusion of the Netflix documentary Gone Girls reveals the heart-wrenching fate of Mari Gilbert, who tragically lost her life in her pursuit of justice. Mari had been advocating for her daughter Shannan to be recognized among the victims of the Long Island serial killer, despite authorities ruling her death an accidental drowning. A significant aspect of the documentary that was glossed over was the nature of Mari’s death, which could have detracted from the documentary’s primary focus.

Mari was fatally stabbed by her daughter, Sarra, in 2016 during what appeared to be an episode of severe mental illness. Sarra, reported to have schizophrenia, claimed to hear voices instructing her that Mari was culpable for Shannan’s death and encouraged her to commit the act of murder. Consequently, Sarra was charged and subsequently convicted of second-degree murder, and she is currently serving a 25-year sentence in a maximum-security facility.
