Two U.S. government scientists charged with smuggling deactivated mpox virus into country

I do this all the time—a casual claim that became evidence of deception
Munster's statement to investigators at the airport, later proven false by testing and charges.

Vincent Munster and Claude Kwe, both virologists at Rocky Mountain Laboratories, were caught with undeclared mpox samples after returning from Congo in January. Munster denied possessing biological materials to investigators, claiming required documents were in his laptop and stating 'I do this all the time.'

  • Vincent Munster and Claude Kwe, virologists at Rocky Mountain Laboratories in Montana
  • Stopped at Detroit Metropolitan Airport in January after returning from Congo
  • Traveling with undeclared, deactivated mpox virus vials without permits
  • Mpox outbreak in Congo linked to over 2,000 deaths

Two scientists at a U.S. government lab face federal charges for smuggling deactivated mpox virus vials from Africa without permits and lying to investigators at Detroit airport.

Two virologists employed at a federal research facility in Montana were charged in federal court this week with smuggling deactivated mpox virus samples into the United States without authorization and then lying about it to investigators. Vincent Munster, who leads the virus ecology section at Rocky Mountain Laboratories in Hamilton, and his colleague Claude Kwe were stopped at Detroit Metropolitan Airport in January after arriving on a flight from Paris, where they had spent nine days in the Republic of Congo conducting research.

When questioned by authorities at the airport, Munster denied that he and Kwe were carrying any biological materials or samples. He told investigators that any necessary documentation was stored on his laptop and added, with apparent casualness, that he performed this kind of work routinely. The FBI later determined these statements were materially false. Testing revealed the two men were indeed traveling with vials of deactivated mpox virus—samples they had neither declared to customs nor obtained permits to transport.

The timing of their return coincided with a significant outbreak in Congo. The disease has been linked to more than 2,000 deaths in the central African nation, though health authorities announced in April that a two-year outbreak had ended. Mpox, formerly called monkeypox, typically causes a rash and fever in infected people, though serious illness can occur. Most people recover completely.

Munster and Kwe are both experienced virologists with extensive backgrounds in mpox research. The criminal complaint does not explain their motivation for bringing the deactivated samples back to their laboratory without proper channels, but their professional focus on the virus suggests the samples were intended for continued study. The vials themselves posed no active threat—they were deactivated—yet federal authorities emphasized that the manner in which they were transported raised serious concerns.

Marcus Sykes, an official with the Office of Inspector General at the Department of Health and Human Services, the parent agency of Rocky Mountain Laboratories, stated that any deliberate concealment and smuggling of biological materials without authorization represents a violation of public trust and could have endangered public safety. The charges underscore the strict regulatory framework governing the movement of pathogenic materials across international borders, even when those materials have been rendered inactive.

Neither scientist responded immediately to requests for comment. They are scheduled to appear in federal court in Missoula, Montana, to face the charges. The case raises questions about oversight and compliance protocols at government research facilities, and whether existing safeguards are sufficient to prevent unauthorized transport of biological samples, regardless of their active status.

Any deliberate effort to conceal and smuggle biological materials into the United States without proper authorization is a breach of the public's trust and could have placed the public at risk.

Why would two experienced scientists risk their careers by smuggling samples they could have requested through official channels?

Model

That's the question no one can answer yet. The complaint doesn't say. They're virologists—they understand the rules. Maybe they thought the samples would be lost in bureaucracy, or maybe they wanted to work on them immediately. We don't know.

Inventor

Does it matter that the virus was deactivated?

Model

Legally and practically, yes and no. It means there was no active biological threat. But it also means they knew exactly what they had and chose to hide it anyway. That's the lie that troubles authorities more than the samples themselves.

Inventor

What does "I do this all the time" tell us?

Model

Either he was genuinely casual about it—suggesting a pattern of behavior—or he was trying to normalize something he knew was wrong. Either way, it's an admission wrapped in false confidence.

Inventor

Could this happen at other government labs?

Model

That's what people will be asking now. If two senior virologists at a major federal facility felt comfortable doing this, what does that say about the culture around biosecurity protocols?
