When federal agents searched the containers at a Miami shipping warehouse, they say they found an arsenal hidden among ordinary household goods and beneath pieces of lead: nine rifles, six pistols, more than 15,000 rounds of ammunition and dozens of firearm components, including 18 unfinished, unserialized AR-style lower receivers that can be used to build privately assembled firearms commonly known as “ghost guns.” Bidjaikoemar “Jerry” Nanhoe who is the prime suspect is now facing federal charges in Miami of smuggling goods from the United States, delivering firearms to a common carrier without providing notice and trafficking in firearms. According to the affidavit from a Homeland Security Investigations special agent, HSI agents assigned to a Miami International Airport cargo task force, working with ATF agents and Miami Beach police detectives, began surveilling Nanhoe after he arrived at MIA aboard Surinam Airways Flight 421 on Aug. 25. The affidavit does not explain what initially drew investigators’ attention to him. The case offers a glimpse into a multi-agency investigation involving HSI, the Bureau of Alcohol, Tobacco, Firearms and Explosives and Miami Beach police — and leaves unanswered some potentially significant questions: What initially drew investigators to Nanhoe? Where did the firearms come from? And who was ultimately supposed to receive them in Suriname?
