Press Release

Queens District Attorney Melinda Katz announced that Lianu Luis Brown Delgado has been charged with weapons possession and other crimes after an investigation led to the recovery of eight guns, including seven ghost guns and more than 100 rounds of ammunition, at the defendant’s Rosedale home. The guns were allegedly made on a 3D printer inside the defendant’s residence and include two assault weapons.

District Attorney Katz said: “As alleged, the defendant amassed a significant collection of ghost guns and 3D-printed weapon parts in his Queens home, placing countless lives in danger. Those who choose to personally manufacture deadly firearms should find other, lawful ways to spend their time. Working alongside our partners in the NYPD, we will continue to investigate and prosecute the illegal production of these untraceable weapons to protect the safety of our communities.”

Delgado, 22, of Edgewood Street in Rosedale, was arraigned today on a 51-count criminal complaint charging him with criminal possession of a weapon in the second, third and fourth degrees, criminal sale of a firearm in the third degree, criminal possession of a firearm, make/transport/dispose/deface weapons and dangerous instruments and unlawful possession of pistol or revolver ammunition.

Queens Criminal Court Judge Srividya Pappachan ordered Delgado to return to court on November 10. He faces up to 15 years in prison if convicted.

According to the charges, the District Attorney’s Crime Strategies & Intelligence Bureau and the NYPD Major Case Field Intelligence Team conducted a seven-month long investigation into the purchase of unserialized firearm components, accessories and manufacturing tools by the defendant. Such components are often used to be made into “ghost guns” and 3-D printed guns.

On Wednesday, a court-authorized search warrant was executed at Delgado’s home and the following items were recovered:

• Seven completed ghost guns:
  • Six 9 mm Glock style pistols with 3D-printed frames, two of which were assault weapons
  • One .380-caliber Ruger with a 3D-printed fire control unit
• One .380-caliber Ruger serialized firearm
• Nine additional frames:
  • Eight 3D-printed Glock style frames
  • One 3D-printed fire control unit for a Ruger style firearm
• Two high-capacity magazines (in addition to 12 lower capacity magazines)
• 100 rounds of 9 mm ammo
• Seven rounds .380-caliber ammo
• One 3D printer

A check of the License and Permit Systems database showed that the defendant does not hold a license to possess or own firearms in New York City and that there are no pistol permit or shotgun and rifle licenses associated with his residence.

Since August 2021, the District Attorney’s Crime Strategies & Intelligence Bureau has conducted investigations that have led to the seizure of 468 firearms including 303 ghost guns, as well as 1,195 high-capacity magazines, 355 additional firearm lower receivers, 17 3D printers and more than 141,750 rounds of ammunition.

In 2024, Queens had the most ghost gun recoveries in New York City for the fourth year in a row and is presently leading recoveries for 2025.

This investigation was conducted by members of the District Attorney’s Detectives Bureau under the supervision of Lieutenant Joseph Oliver, Sergeant David Moore, and under the overall supervision of Chief Instigator Robert LaPollo; as well as NYPD Major Case Field Intelligence Team Detectives Mike Billotoo, Paul Molinaro, John Schultz, Christopher Thomas, John Uske and Sergeant Gregg Minardi, Captain Christian Jara, under the supervision of Deputy Chief Courtney Nilan of the Intelligence Division.

The District Attorney also thanks members of the Kings County District Attorney’s Gun Violence Suppression Bureau, New York State Police and the United States Postal Inspectors.

Assistant District Attorney Attaul Haq, of the District Attorney’s Crime Strategies and Intelligence Bureau, is prosecuting the case with the assistance of Intelligence Analyst Megan Kane and Supervising Intelligence Analyst Victoria Filipe, under the supervision Assistant District Attorney Shanon N. LaCorte, Bureau Chief, Brandi S. Kligman, Deputy Bureau Chief, and under the overall supervision of Executive Assistant District Attorney for Investigations Gerard Brave.
