According to a CrimeSpace investigation, the key suspect in the decade-old Gilgo Beach murders, Rex Heuermann, has an extensive footprint stretching across the nation. Public records reveal that the Long Island man maintained residences in no fewer than seven states.

His New York connections are extensive with him holding at least three residences over the years in Massapequa Park, Freeport, and the heart of midtown Manhattan.

But Heuermann’s property portfolio reaches far beyond the Empire State. He has staked his claim in real estate across the nation, owning properties that extend from the east coast to the west.

These properties, some of which are rentals, pepper locations such as North Reading, Massachusetts; Phoenix, Arizona; West Warwick, Rhode Island; Beverly Hills, Michigan; North Brunswick, New Jersey; Burlington, New Jersey; and as far as Las Vegas, Nevada.

What’s more, public records reviewed by CrimeSpace also show that he holds hunting licenses in the frontier state of Alaska and New York. Furthermore, he possesses a license to carry in New York, hinting at a side of Heuermann that speaks to an obsession for firearms, something corroborated by his staggering collection of 92 firearms, as previously mentioned.

This web of residences and licenses paints a vivid—and disturbing—picture of the man now standing in the eye of the storm, a key suspect in one of the most haunting murder cases in recent history.

Authorities on Friday indicted a man named Rex Heuermann in connection to the infamous Gilgo Beach murders. Living in Massapequa Park, a Nassau County village on Long Island, the 59-year-old Heuermann pleaded not guilty to three counts of first-degree murder.

Suffolk County Police Commissioner Rodney Harrison portrayed Heuermann as a “demon walking among us,” a predator who brought untold pain and suffering to families.

The extent of Heuermann’s engagement with the case is deeply troubling, as revealed by prosecutors and investigators. They had maintained a veil of secrecy over many aspects of the case, suspecting that Heuermann had been following developments closely. They believed that revealing information could potentially tip off the suspect and hinder the investigation.

According to court documents, Heuermann had been scouring the internet for details related to the case, including information about the task force established to probe the Gilgo Beach murders, the “Long Island serial killer,” and the victims themselves.

One of the key pieces of evidence leading to Heuermann’s arrest was a pizza crust he discarded on Fifth Avenue, Manhattan, in January. After forensic examination by two separate labs, a DNA match was established between the crust and hair found on burlap used to tie up victim Megan Waterman.

This methodology recalls a similar tactic employed in the 2010 prosecution of the serial killer Lonnie Franklin Jr., in Los Angeles, where discarded pizza crust was used to extract DNA.

Heuermann, according to District Attorney Tierney, holds permits for an alarming number of firearms—92 in total. Their whereabouts are still unknown, and a number of search warrants are expected to be filed or executed in the case. Tierney suggested that the guns might be found in Heuermann’s residence on Long Island, specifically within a large safe.

Heuermann’s continued involvement with sex workers triggered fears among law enforcement that he could potentially kill again. According to Suffolk County District Attorney Tierney, Heuermann had been using fictitious email addresses, identities, and burner phones. This eventually tipped the balance in favor of public safety and led to his arrest.

Officials reiterated their damning portrayal of Heuermann at a press conference, thanking the members of the task force for their efforts that led to the suspect’s capture.

Lynn Barthelemy, whose daughter was a victim, expressed her wish that Heuermann should “suffer at the hands of other inmates” in prison in an interview with NBC News. She described death as too easy for him.

Heuermann’s persona is contradictory: to some of his neighbors, he was an “everyday businessman,” commuting to work in a suit and briefcase, while to others, his dilapidated house seemed eerie, even creepy.

Heuermann, dressed in business casual attire, appeared before a Long Island court, vehemently claiming his innocence. Despite his tearful denial, he faces multiple murder charges and is held without bail.

Notably, Joseph Brewer, who was one of the last to see Shannan Gilbert – the woman whose disappearance led to the discovery of the Gilgo Beach victims – expressed relief at Heuermann’s arrest. Brewer has been cooperating with law enforcement throughout the search for Gilbert and shared his hope for justice for the victims’ families.
