Key Discussion Points & Insights

Introduction: The Case and Its Impact

• [00:00-01:30]
  • In 2010, a young woman’s disappearance on Long Island led police to a far more disturbing discovery: the skeletal remains of multiple women, all sex workers, off a busy parkway near Gilgo Beach.
  • Over time, police realized they'd uncovered a serial killer’s dumping ground.
  • The suspect was unidentified (dubbed LISK: Long Island Serial Killer) until the 2023 arrest of Rex Heuermann, an architect and father.
  • With the trial looming and a possible plea on the horizon, Anne welcomes Kristen Thorne for a retrospective account.

Kristen’s Firsthand Reporting Experience

• [02:14-04:08]
  • Kristen recalls being a junior reporter covering the initial discoveries:
    • "I really do remember it like it was yesterday. It was freezing. It was dark. You have to understand, this area of Gilgo beach...is very desolate and extremely dark. And you have the moon. And that's about it." — Kristen Thorne [02:27]
  • Reporters joked, half seriously, about locking the doors to their trucks amidst fear and uncertainty.
  • The atmosphere: Windy, cold, pouring rain, and the heavy, constant sense of unease.

Discovery Timeline and Crime Scene

• [05:27-07:59]
  • Remains had been found in the area even before the notorious "Gilgo Four," but the pieces weren’t connected.
  • Breakthrough came after the disappearance of Shannon Gilbert (2010); police, while searching for her, found other bodies.
  • "They ended up—a canine officer decided to train his dog and go out one day. And lo and behold, while looking for Shannon Gilbert, he finds one of these bodies, one of the Gilgo 4. And that then led to the finding of the other three." — Kristen Thorne [06:09]
  • Multiple victims discovered, including an unidentified woman, a toddler, and an Asian male—some still not definitively linked to the now-charged suspect.

Investigative Challenges and Police Controversies

• [07:59-12:39]
  • Prolonged periods without new information; the case became local “lore.”
  • Suffolk County police chief at the time, James Burke, was adamant about excluding the FBI—later jailed for unrelated charges.
  • Media and public frustrations over the lack of transparency and police communication.
  • Police held critical evidence (like burlap and duct tape) close to the vest:
    • "For years, there were these, again, rumors flying around about what, what. But police were clear that…Why do police not tell you that it was burlap and duct tape?...Because when they get a suspect in custody, they need…information that only the suspect would know." — Kristen Thorne [11:05]

Victim Blaming and Delays

• [12:39-14:09]
  • Quick identification and reporting that several victims were sex workers.
  • Shannon Gilbert’s disappearance was initially dismissed by police, delaying crucial search and investigation—demonstrates bias in response to marginalized victims.
  • “Because she was a sex worker, delayed the Discovery of the Gilgo 4.” — Kristen Thorne [13:10]

Law Enforcement Stalemate and Change

• [14:09-18:54]
  • Reporters pushed hard against police stonewalling and refusal to involve the FBI.
  • Anne on police politics: "That's just politics, Kristen. I mean, really, like, there's these women who have these families…And you've got people playing politics." [16:32]
  • After Burke, Geraldine Hart took steps toward improved transparency, but the FBI was initially unwilling to return.
  • Turning point: Rodney Harrison’s appointment as Suffolk County Police Chief in 2021, forming a cross-agency task force solely focused on Gilgo.

The Break in the Case: Diligent Police Work

• [18:54-22:10]
  • Rodney Harrison organized all case evidence in a “war room,” digitizing files and dedicating full-time investigators—a key difference from prior diluted attention.
  • A female state police trooper noticed an old witness statement about Amber Costello—including a description of a “huge man” and a green Chevy Avalanche.
  • "So now you've got this state police trooper in 2022 Looking at this, and she goes, did you guys see this, this report about the guy with the big huge man that was seen with Amber in this green Chevy Avalanche and that they all jumped on it..." — Kristen Thorne [21:37]
  • Quickly, this clue led them to Rex Heuermann, who had been among several hundred early-persons of interest.

Technical Breakthroughs: Cell Phones and Movement

• [24:37-25:21]
  • The case leveraged cell phone tower pings and burner phone tracing, correlating movements between Heuermann's home, victims, and areas in New York City.
  • "The pinging of these burner phones between Massapequa park, which is where Rex Herman was living at the time...And so when police started to look at these burner phones, they started to see that they were pinging and that the phones of the victims were pinging around the same places." — Kristen Thorne [24:37]

The Suspect: “Hiding in Plain Sight”

• [25:21-28:43]
  • Heuermann lived an ostensibly normal life: architect, family man, daily NYC commuter—the “monster next door.”
  • His home, however, stood out: "It is by far...the house that, like, no one went trick or treating to. It was the house everybody stayed away from."
  • Anne: "He does not look, or who does look like a serial killer. But, I mean, this was weird. This was super weird." [27:23]
  • Kristen’s vivid recounting of the moment the arrest hit the newsrooms: the disbelief, rush to the scene, and then the overwhelming confirmation as law enforcement descended.

Notable Quotes & Memorable Moments

• On official acknowledgment of a serial killer:

  • "Finally, the chief of Suffolk police At the time came out and said, we believe we have a serial killer on our hands. And that is, once you hear a chief of police say that, you know, that you are dealing with a pretty serious situation." — Kristen Thorne [08:10]

• On the significance of new policing methods:
