Long Island’s alleged ghost gun kingpin arrested in Suffolk County’s biggest weapons bust ever

An alleged gun smuggler has been arrested for making and selling homemade firearms and accessories with 3D printers in what Suffolk County is calling its largest ghost gun bust in history. 

Daniel Probeck, 35, was arraigned Wednesday after a long-term investigation led cops to his Medford house where they seized over 110 guns, nearly 70 suppressors, 12 3D printers, and enough gun parts and ammo to stock a small army. 

“This defendant was not simply a firearms collector,” Suffolk County District Attorney Ray Tierney said in a statement Wednesday. “[Probeck] is alleged to have been building and selling illegal weapons for profit.” 

Tierney also applauded the joint work between his office and police investigators for “getting this source of illegal weapons off the street.”

Beginning in March 2025, the DA and the police launched a joint probe into Probeck for illegally selling ghost guns, which are illegal guns with no serial number. 

Probeck was later arrested at his home in June after allegedly selling four firearms, three of which were assault rifles, to undercover cops for an undisclosed amount of money on multiple different occasions starting back in March. 

On the day of his arrest, police executed a search warrant of his home that allegedly doubled as a weapons manufacturing plant and found the arsenal — charging Probeck with several counts of criminal sale of a firearm, and multiple related possession charges, for selling and illegally possessing the guns at his home.

During the search, investigators recovered assault weapons outfitted with banned features under New York law — like threaded barrels, pistol grips, collapsible stocks, flash suppressors, and other aftermarket parts, prosecutors said.

Probeck pleaded not guilty and is being held on $500,000 cash bail, a $2 million bond, or a $3 million partially secured bond while the case is pending.

Represented by attorney John Loturco, Probeck is due back in court on August 5 and faces up to 25 years in prison if convicted on the top count.

Loturco said his client is a lifelong Suffolk resident with no prior criminal convictions, a father of two who’s been with his wife for 17 years and a 12-year member of the steamfitters union.

“We entered a plea of not guilty to the Indictment, and we will meticulously scrutinize the evidence by reviewing the discovery to assess our strategy going forward,” Loturco said in a statement.
