"There is insufficient information to determine a definite cause of death, but the autopsy findings are consistent with homicidal strangulation." — Dr. Michael M. Badden
"There's a difference between souvenirs and trophies. Souvenirs are something that he keeps privately to himself, to remind himself, and encourage the fantasies that he will have as he's reliving these experiences, these offences. Trophies are something you show off." — Jim Clemente
"It is my opinion based on the circumstances of Shannon's death, and on the materials I have reviewed, that there is no evidence she died of a natural disease, of a drug overdose, or of drowning." — Dr. Michael M. Badden
This episode details the significant developments in the Long Island serial killer (LISK) investigation, centering on the arrest of Rex Heuermann in connection with the murders of Melissa Bartholomey, Megan Waterman, and Amber Costello. The report traces the investigation's origins back to the disappearance of Shannon Gilbert in 2010, whose initial 911 call revealed a panicked woman fearing for her life. The discovery of multiple sets of remains on Gilgo Beach, initially identified as four women (the "Gilgo Four") with similar profiles as sex workers, marked the beginning of a complex and sprawling investigation that later encompassed remains linked to cases dating back to the 1990s.
The narrative highlights the investigative challenges, including potential corruption within the Suffolk County Police Department, particularly the actions of former Chief James Burke, which are believed to have impeded progress and collaboration with federal agencies. Advancements in forensic technology, including DNA analysis and the utilization of cell phone location data, proved instrumental. The episode details how the tracking of burner phones and Rex Heuermann's own cell phone, coupled with American Express records revealing dating app activity, led investigators to establish a strong connection between Heuermann and the victims.
Further forensic analysis, including DNA testing from hair found on victims and on discarded items from Heuermann's residence, corroborated his connection to the crime scenes. The report also touches upon the case of Shannon Gilbert, with expert analysis suggesting her death was consistent with homicidal strangulation, contradicting earlier findings of accidental death. The arrest of Heuermann, while a major breakthrough, opens new avenues of inquiry into his potential involvement with other victims and the broader context of criminal activity in the area.
