Creepy alleged serial murderer Rex Heuermann was obsessed with firearms and kept a serious weapons cache in a concrete basement room, which almost nobody was allowed to see.
However, one of the few admitted was his friend David Jimenez, a fellow weapons enthusiast who used to go with hulking Heuermann to the firing range.
“I was in that famous ‘gun room’ several times. He told me, ‘You’re one of only four people ever to be in this room’. And I said, ‘Wow, okay, I’m privileged’,” said Jimenez, who appears in new Peacock documentary “The Gilgo Beach Killer: House of Secrets.”
“Heuermann has a fascinating collection, and knows everything about each gun. When it was used, if it was altered, he’s super knowledgeable when it comes to World War I, World War II, the Korean War, anything with firearms. I was fascinated by that, because I am too.
“And its ironic, because if he did do these killings, it doesn’t appear he used a firearm,” Jimenez added to The Post.
After Heuermann was arrested in 2023, leading to him being charged with the murders of seven sex workers, police raided the family home and recovered “approximately 279 weapons” in the “cluttered” residence, including “quite a few long guns” and 92 handgun permits.
Suffolk Police Commissioner Rodney Harrison told CBS New York at the time the vault had a large iron door. Authorities later said some of the weapons were there illegally without a permit.
The family petitioned to get them back in 2023 so they could sell them, although its unclear if that happened or if they are still in police custody.
Heuermann’s wife, Asa Ellerup, and two grown-up children are not thought to have been allowed in the gun room.
Jimenez clarified that while the number of firearms his pal owned sounds like a lot, for a serious collector it was in no way unreasonable.
“He’s been collecting since he was 18 years old and kept on adding. Maybe 90% of them never got shot. A lot of them were just pieces for the collection.
“In the gun world, many collectors will have as many as they can afford. And then they gain value, so it’s a good investment. An interest and a hobby.”
Heuermann also stands accused of dumping the remains of the seven people he is charged with murdering across Long Island in a bloody spree between 1993 and 2011. He has pleaded not guilty to all the charges against him and is currently awaiting trial.
