Suffolk County prosecutors delivered a significant update in a long-standing cold case Tuesday, announcing that DNA evidence has cleared Rex Heuermann of involvement in the 1994 death of Colleen McNamee, an elderly resident whose case had drawn parallels to the Gilgo Beach investigations. Heuermann, the architect accused in the deaths of seven women found along Long Island’s Ocean Parkway, remains the prime focus of the broader probe but faces no charges in McNamee’s case. The development, stemming from advanced forensic testing, highlights the complexities of linking disparate incidents in a region scarred by unsolved tragedies.

McNamee, 39 at the time of her passing, was discovered in a wooded area near the former Kings Park Psychiatric Center in December 1994. Authorities initially classified her death as a homicide based on the circumstances, but the case stalled amid limited evidence. Fast-forward three decades, and renewed scrutiny arose when Heuermann emerged as a suspect in the Gilgo Beach killings. Investigators, wary of overlaps, re-examined biological samples from McNamee’s scene, including trace DNA collected during the original probe.

The Suffolk County Crime Lab’s analysis, conducted at the request of convicted killer John Bittrolff—who had been eyed in McNamee’s case—yielded a clear result: Heuermann’s genetic profile did not match the evidence. “This exclusion provides important clarity for all involved,” Suffolk County District Attorney Raymond Tierney stated during a briefing in Riverhead. Tierney emphasized that while the Gilgo task force continues its work, distinguishing between cases prevents misallocation of resources and honors the victims’ memories accurately.

Bittrolff, a Manorville carpenter serving life sentences for two 1990s murders, petitioned for the retesting as part of his ongoing appeals. His attorneys argued that similarities in disposal sites and victim profiles warranted a fresh look, potentially implicating Heuermann and bolstering Bittrolff’s innocence claims. Instead, the lab’s findings reinforced Bittrolff’s connection to McNamee while definitively ruling out Heuermann. “We’ve advocated for this science to speak the truth,” said Bittrolff’s lawyer, William Keahon, in a statement to local media. The Legal Aid Society, representing Bittrolff, hailed the outcome as a win for forensic integrity.

Heuermann’s legal team seized on the news, with defense attorney Michael Brown calling it “yet another blow to the prosecution’s overreach.” Brown has long maintained that Suffolk authorities rushed to tie Heuermann to every unsolved case on Long Island, a tactic he deems prejudicial. In court filings last month, Brown cited the McNamee exclusion as evidence of flawed investigative assumptions. Heuermann, 62, has pleaded not guilty to charges involving the Gilgo Four—Melissa Barthelemy, Megan Waterman, Amber Costello, and Maureen Brainard-Barnes—plus Jessica Taylor, Sandra Costilla, and Valerie Mack. Those indictments, spanning 1993 to 2010, rely on hair DNA, phone records, and a purported “planning document” seized from his Massapequa Park home.

The Gilgo Beach saga began in December 2010 when a police search for a missing escort uncovered partial remains wrapped in burlap along Ocean Parkway. Over the next few months, 11 sets of bones surfaced, prompting fears of a serial perpetrator. Heuermann’s arrest in July 2023 shattered the quiet suburb where he lived with his wife, Asa Ellerup, and their two children. Prosecutors allege he targeted women in sex work, using burner phones to arrange meetings and disposing of remains in remote dunes. A raid on his home uncovered over 200 firearms, bondage materials, and digital searches mirroring the victims’ conditions.

McNamee’s case, though unrelated, underscores the era’s investigative hurdles. The Kings Park facility, a sprawling psychiatric complex closed in the mid-1990s, was a hub for vulnerable patients, many navigating outpatient care in isolated areas. McNamee’s loved ones described her as a devoted mother and community volunteer, far from the profiles in the Gilgo indictments. Her family, who attended Tierney’s announcement, expressed mixed relief. “We’ve carried this weight for 31 years,” said her sister, Patricia McNamee, through tears. “Knowing Rex wasn’t involved brings some peace, but it doesn’t bring Colleen back. We just want the real answers.”

Tierney’s Cold Case Unit, formed in 2024, has prioritized retesting in light of Heuermann’s profile. The lab’s exclusion mirrors a pattern: earlier this year, Heuermann was cleared in the 1996 death of an 82-year-old assault survivor at the same psychiatric center. Yet prosecutors stress that Gilgo evidence remains robust. Hair fragments on Costilla and Taylor matched Heuermann’s mitochondrial DNA, while truck tire treads and witness sketches align with his Chevrolet Avalanche. A recent court filing declared the case trial-ready, with jury selection eyed for early 2026.

Heuermann’s defense counters with motions to suppress key evidence, including the controversial “familial DNA” search that flagged him via a relative’s public genealogy database. Brown argues the technique invades privacy and lacks chain-of-custody rigor. In a Peacock docuseries airing this fall, Ellerup defended her husband vehemently: “Rex couldn’t harm a soul. He’s the father who built forts with our kids.” She and the couple’s adult children have filed a $10 million lawsuit against authorities, claiming the arrests upended their lives without due process.

Long Island’s history of cold cases fuels public fascination and frustration. Bittrolff’s 2017 conviction for killing Rita Tangredi and Colleen Gilbert—bodies found in nearby woods—drew initial links to McNamee due to geographic proximity. Former prosecutor Robert Biancavilla once speculated Bittrolff might connect to Gilgo, a theory now debunked.

Community reactions poured in online, with #GilgoUpdate trending on X. Supporters of Heuermann’s innocence shared memes questioning the DA’s motives, while victims’ advocates urged focus on the charged cases. “Exclusions are good science, but they don’t erase the pain of the seven families still waiting,” posted the National Center for Missing & Exploited Children. Tierney, facing reelection in 2026, defended his office’s pace: “We’re not chasing headlines; we’re chasing justice.”

As winter approaches the barrier island’s windswept shores, the probe presses on. Heuermann, held without bail at Riverhead Correctional Facility, awaits a bail hearing next month. His next court date, set for December 10, will address evidence admissibility. For McNamee’s kin, the clearance closes one door, though the search for her true circumstances lingers. In a statement, Patricia McNamee added, “Colleen deserved better than silence. This is a step, but not the end.”

The Gilgo task force, comprising 30 detectives and analysts, vows exhaustive review of remaining remains, including the “Asian Doe” child and unidentified Jane Doe No. 7. Funding from a $5 million state grant sustains the effort, with Tierney eyeing expansions to Nassau County cases. Experts like former FBI profiler Brad Garrett note that serial investigations thrive on patience: “One exclusion sharpens the focus on the links that hold.”

Heuermann’s professional life, once anchored in Manhattan architecture, now serves as exhibit fodder. Colleagues recall a meticulous planner, traits prosecutors tie to the seized “blueprint”—a spreadsheet outlining victim selection and disposal. Defense experts dismiss it as innocuous note-taking. As hearings loom, the case tests Suffolk’s justice system, balancing closure with constitutional safeguards.

For the accused, the McNamee ruling offers a rare reprieve amid mounting charges. Heuermann’s sister, who visited him last week, told outlets, “He’s fighting every day. This proves they’re wrong about everything.” Yet with seven counts of second-degree murder carrying life terms, optimism tempers caution. Brown plans appeals on the DNA methodology, citing precedents from California cold cases.

Long Island residents, from Massapequa Park barbershops to Southampton diners, dissect the twists over coffee. “It’s like a bad dream that won’t end,” sighed one local shop owner. Memorials for the Gilgo victims dot Ocean Parkway, wildflowers tied to guardrails where bones once lay hidden. McNamee’s family, meanwhile, honors her with annual beach cleanups, turning grief into guardianship.

This latest chapter reaffirms forensic science’s pivot: exclusions, though anticlimactic, refine the narrative. Tierney closed his remarks with resolve: “Every thread matters. We’ll follow them all.” As November fog rolls in, Long Island holds its breath—for verdicts, for vindication, for the quiet that justice might finally bring.
