A Queens man is facing a sweeping indictment after authorities discovered a stockpile of homemade ghost guns and ammunition inside his Rosedale home, prosecutors announced Thursday.
According to the Queens District Attorney’s Office, 22-year-old Lianu Luis Brown Delgado has been charged in a 51-count indictment after investigators uncovered seven completed ghost guns, a .380-caliber Ruger handgun, eight 3D-printed Glock-style frames, and roughly 100 rounds of ammunition.
“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,” said Queens District Attorney Melinda Katz.
Ghost guns — untraceable firearms assembled from kits or 3D-printed components — have become a growing concern for law enforcement because they lack serial numbers and are nearly impossible to track.
Delgado’s arrest came after a seven-month investigation into illegal gun manufacturing and sales. Police executed a search warrant at his home on Wednesday, uncovering the illegal arsenal.
He faces multiple charges, including criminal possession of a weapon, criminal sale of a firearm, and unlawful possession of pistol or revolver ammunition. Delgado is being held without bail and is scheduled to return to court on November 10.
Authorities say the arrest is part of a broader effort to curb the rise of ghost guns across the New York metro area. In a separate case earlier this year, Daniel Probeck, 35, of Long Island, was charged after police allegedly found 110 guns, nearly 70 suppressors, 12 3D printers, and a large cache of weapon parts at his home. That case remains ongoing.
The investigation comes as federal and local officials, under the leadership of President Trump, continue to prioritize tougher enforcement against illegal firearms and the growing threat of untraceable weapons nationwide.
