Long Island man with world’s largest serial killer collection reveals how alleged Gilgo Beach slayer Rex Heuermann items fare in market: ‘Hot item’
They’re dying to get their hands on this stuff.
Any creepy memorabilia linked to accused Gilgo Beach Killer Rex Heuermann could fetch an arm and leg on the macabre collectable market, according to a well known Long Island dealer who has the world’s largest collection of serial killer items.
“Right now, he’s a hot item,” David Adamovich, the 78-year-old Freeport resident, told The Post.
“I’d like to get his car,” he added of Heurmann’s dark green Chevrolet Avalanche that drew police to the Massapeuqa murder suspect.
The vehicle will likely cost thousands of dollars above street value, and even just the license plate “would be a great collectable” if it were ever made accessible to the public, according to the eerie expert.
Regarding everyday items, “anything they can tie to the murders would be great” for a killer keepsake, the collector said. Sadly for sickos, Adamovich doubts the pizza box Heuermann’s DNA was found on will never be accessible outside of the law enforcement world.
He knows killer tchotchkes when he sees them.
Adamovich is in possession of more than 9,000 famous criminal items such as sketches of Charles Manson from his fellow inmates, a yearbook with Lee Harvey Oswald’s portrait, clippings of Ted Bundy’s hair, the bra and panties of Susan Smith, and written letters by Jeffery Dahmer and several other notorious murderers.
As a known dealer in famous killer’s items, Adamovich is already getting calls from eager folks itching to buy or appraise something belonging to the world’s most notorious NYC architect.
“I’m sure his stuff is going to be of value to current collectors,” he said, noting that items will only skyrocket in price in the event Heuermann is formally convicted of murder.
Until that is the case, however, Adamovich won’t think about personally investing in Rex merch.
Hot Rex items on the murder market
Adamovich said, “there is no blue book” on set values of killer-used or affiliated belongings, but future letters Heuermann — if convicted — would write from prison are likely going to go for a few hundred dollars apiece, especially if hand-signed.
They are also the easiest to authenticate, according to Adamovich, who said many peddle phony objects.
Since Adamovich’s band of Bundy’s hair is a “more prized” possession, he wouldn’t be surprised if Heuermann locks or other hygienic discards also cost a pretty penny.
However, old yearbooks from his days at Berner High School will be in high demand, and professional papers from Heuermann’s eponymous architecture firm will likely lure in killer connoisseurs as well.
“Any files, anything that has his name on it, anything signed by him, any of his work…people may have plans he signed off on,” said Adamovich. “All of that is going to be of value.”
It isn’t uncommon for obsessed individuals to shell out big time on the strange collectibles, either. People have paid thousands to Adamovich when he has sold select one-offs like paintings by John Wayne Gacy.
There’s no surprise that he works an odd job as well. Adamovich is a world record-holding knife thrower — he goes by “the great Throwdini” as a stagename — and came in possession of his entire collection about a decade ago.
He acquired all of the creepy collectables at an undisclosed sum from the estate of a corrections officer friend he knew in the magic community who had passed. While on the job for two decades, Adamovich’s friend had several chances to get behind the scenes access to the killers themselves or connected fellow prison workers.
“He would just squirrel everything away in boxes in a storage unit,” said Adamovich. “And nobody ever knew about it.”
Out of everything, which is kept in a confidential location, Adamovich said his most valuable items are his 70-plus boxes of serial killer letters. He is digitalizing them as an educational resource for forensic professionals and has used the chilling messages to lecture investigators.
“I’m guessing [a value of] maybe $300,000 for the letters,” he said.
