In an unsettling development in the case of Rex Heuermann, the primary suspect in the notorious Gilgo Beach murders, investigators have unearthed a soundproof room in his basement, believed to be the scene of at least one horrific crime.

Rex Heuermann, a 59-year-old architect from Manhattan, has found himself at the center of a chilling investigation as the main suspect in the infamous Gilgo Beach murders. The case took a sinister turn when investigators discovered a soundproof room in the basement of Heuermann's Long Island home. The room, they believe, could be the grim setting where at least one victim met a tragic end.

A former colleague of Heuermann shared with The New York Post that Heuermann once took a leave of absence from his job to construct a concrete-lined vault in his family's residence. The purpose of this vault remains shrouded in mystery, with speculation rife as to whether it served as a chamber of death or a storage space for Heuermann's extensive collection of firearms.

Delving into the enigma of Heuermann's basement vault

The former colleague described the vault as more than just a concealed room. It was a "serious vault" with a heavy-duty safe door, encased in a significant amount of concrete. The walls were reportedly 2 to 3 feet thick, suggesting a substantial effort to soundproof and secure the room.

Heuermann, a married father of two, has been charged with the murders of three women and is the prime suspect in a fourth killing.

These murders are all part of the infamous 13-year-old "Gilgo Four" murders. The investigation has been ongoing for 11 days, with New York state troopers and Suffolk County investigators meticulously searching Heuermann's home.

A neighbor's disturbing account of Heuermann

Robert Musto, a retired Long Island Rail Road worker and longtime neighbor, described Heuermann as a "wacko". He revealed that police had informed him of the soundproof room in Heuermann's basement, leading him to question its purpose.

"They're saying there's evidence he killed at least one of the girls down there,"

Musto said, referring to the information provided by the police. The investigators are reportedly focused on the soundproof room but are also examining the entire property.

The tragic victims of the Gilgo beach murders

The arrest of Heuermann is tied to the so-called "Gilgo Four," four women whose bodies were found wrapped in burlap within days of each other in late 2010. The victims were Melissa Barthelemy, Maureen Brainard-Barnes, Amber Lynn Costello, and Megan Waterman.

All four women worked as escorts, and authorities have stated that Heuermann was a frequent solicitor of sex.

In addition to the "Gilgo Four," seven other bodies were discovered near the site, which remain part of unsolved cases. These victims included a 2-year-old girl, a young Asian man, and several unidentified women.

Community reaction to the ongoing investigation

The local community has been supportive of the investigation, with residents expressing their desire for justice for the victims. Kathy Huber, a local who went to high school with Heuermann, stated that the community, which consists of many cops and firemen, is okay with the disruption caused by the investigation.

"With these girls, with these victims, please, take your time and get justice for these women and these families,"

Huber said, addressing the authorities. The sentiment is echoed by other residents who are eager for the truth to be uncovered and justice to be served.

Heuermann's arrest and the charges against him

Heuermann was arrested outside his Midtown Manhattan office on July 13 and charged with the murders of Melissa Barthelemy, Megan Waterman, and Amber Lynn Costello. Police also believe he is linked to the death of Maureen Brainard-Barnes, the last of the "Gilgo Four."

Since his arrest, police have removed a truckload of items from his family home, including a creepy, child-size doll with blond braids encased in glass and wood, a portrait of a disfigured woman, and a cache of guns. His wife, who is said to be "disgusted" and "embarrassed" by his arrest, filed for divorce last week.

Despite the mounting evidence and charges against him, Heuermann has pleaded not guilty in court. His lawyer has hinted that police have ignored other, "more significant" clues leading to other suspects.
