Massive Cache of Illegal Weapons Seized in Medford | Suffolk County District Attorney's Office

Suffolk County District Attorney (DA) Squad Investigators seized over 112 illegal firearms, twelve three-dimensional printers, 67 suppressors, ammunition and machinery used to allegedly build guns at Daniel Probeck’s Medford residence.

This is the largest ghost gun seizure in Suffolk County history.

Suffolk County District Attorney Raymond A. Tierney announced that a long-term investigation into an alleged gun trafficking operation in Suffolk County, conducted by the DA’s Office in partnership with the Suffolk County Police Department (SCPD), has resulted in the indictment of Daniel Probeck, 35, of Medford, for Criminal Sale of a Firearm, and several related charges, for allegedly selling and illegally possessing firearms at his Medford residence.

“This defendant was not simply a firearms collector, he is alleged to have manufactured and sold illegal firearms,” said Tierney. “This defendant is alleged to have been building and selling illegal weapons for profit. I applaud the work of my office and the SCPD on getting this source of illegal weapons off the street."

According to the investigation, beginning in March 2025, members of the SCPD and the DA’s Office launched a probe on the defendant for allegedly illegally selling un-serialized illegal guns in Suffolk County. During the investigation, Probeck allegedly sold multiple firearms to an undercover police officer on multiple occasions in exchange for cash.

On June 12, 2025, Probeck was arrested and a search warrant was executed at his residence in Medford. During the search, members of the SCPD recovered over 100 firearms, including alleged assault weapons equipped with cosmetic and accessory features banned in New York State, such as threaded barrels, pistol grips, telescoping stocks, collapsible stocks, flash suppressors and other after-market components.

There was also a variety of ammunition recovered, along with 67 sound suppressors, 12 three-dimensional printers, and an assortment of unfinished gun components and tools used to manufacture weapons.

On July 9, 2025, Probeck was arraigned for the following charges:

  1. One count of Criminal Sale of a Firearm in the First Degree, a Class B violent felony;
  2. One count of Criminal Possession of a Weapon in the First Degree, a Class B violent felony;
  3. One count of Criminal Sale of a Firearm in the Second Degree, a Class C violent felony;
  4. One count of Criminal Possession of a Weapon in the Second Degree, a Class C violent felony; and
  5. Four counts of Criminal Possession of a Weapon in the Third Degree, Class D violent felonies.
Justice Horowitz ordered Probeck held on $500,000 cash, $2,000,000 bond, $3,000,000 partially secured bond. Probeck faces 25 years in prison if convicted.
