Serial Killer Rex Heuermann: Judge Orders Transfer of Dozens of Weapons for Possible Firearm Charge

In the meantime, while Nassau County authorities consider charging Long Island serial killer suspect Rex Heuermann with gun possession, a Suffolk County, New York, judge has decided to allow the transfer of nearly 300 firearms taken from his home.

Heuermann was detained on July 13 and charged with committing the murders of three women discovered dead on Gilgo Beach over a decade ago. 

He is a suspect in the death of a fourth woman, and detectives are looking into if there is a link between the Manhattan architect and a number of other deaths on Long Island and in other places where he has held property.

Following a ten-year search for the notorious Gilgo Beach serial killer, Heuermann was dramatically arrested on July 13 outside his Fifth Avenue offices in Manhattan.

Throughout his thirty-year career as an architect, he claimed to have strangled three women and harassed their relatives via phone calls, frequently from his New York office. He also cited Nike, American Airlines, and Target among his clients.

280 Firearms Discovered at Rex Heuermann Park Home

After his arrest, investigators conducted a thorough search of his Massapequa Park home and discovered over 280 firearms, at least 41 of which were unregistered, including 26 handguns and 15 assault weapons. Ten illicit high capacity magazines were also taken by investigators.

The “proper jurisdiction” for any gun charges, according to the prosecution, is Nassau County, which is home to Heuermann.

After a 30-day period, State Supreme Court Justice Richard Ambro stated on Friday that the weapons could be brought to Nassau County.

Numerous firearms taken from Heuermann’s residence were antique pieces. According to court documents, the authorities also found survivalist supplies, gunpowder, and ammunition boxes.

Although it is unclear at this time if they will file an appeal, Heuermann’s attorneys objected to the items being moved to Nassau County. 

Lawyers for Asa Ellerup, Heuermann’s spouse, also objected to the transfer. They argued that Ellerup’s divorce proceedings should be used to distribute the collection as “marital assets.”
