The detectives moved in after watching a customer buy cocaine and then hop into a cab, Passaic County Sheriff Richard H. Berdnik said.
Working with the county prosecutor's office, the investigators raided the now-former River Multi Services shop on River Street and a nearby apartment shared by Steven A. Mejias-Escoto, 36, and Andry Hernandez-Paulino, 29, in the city's Bunker Hill section, Berdnik said.
Detectives made their move after stopping a cab and arresting passenger Juan P. Varona, also of Paterson, shortly after he bought cocaine from the couple, the sheriff said.
Do-it-yourself "ghost guns” -- made from kits of parts and tools -- aren't stamped with serial numbers registered with a federally licensed manufacturer, bypassing background checks and making it all but impossible for authorities to trace to their buyers.
In addition to the drugs and illegal firearm, sheriff's detectives seized $15,259 in suspected proceeds, Berdnik said.
Mejia-Escoto and Hernandez-Paulino were sent to the Passaic County Jail after being charged with several drug offenses, he said. Varona was released pending a hearing.
