Scientists Accused of Smuggling Mpox Samples, Lying to Feds
Two government scientists are facing federal charges after authorities say they tried to bring biological samples of the mpox virus into the United States without proper approval and then lied about it when questioned.
The case centers on Vincent Munster, who serves as the chief of the virus ecology section at Rocky Mountain Laboratories in Montana, and fellow researcher Claude Kwe. According to federal court documents, the two were detained at Detroit Metropolitan Airport in January after arriving from Paris. They had just returned from a nine-day trip to the Republic of Congo.
Agents say they found undeclared vials of deactivated mpox virus in their possession. Even though the material was not infectious, federal officials say the samples still required the right permits and approvals before being transported into the country.
At first, Munster “adamantly denied” having any biological materials with him, according to an FBI affidavit. Investigators later say testing showed both men did in fact have samples with them. The complaint also says neither scientist had secured the required paperwork.
One of the more striking details in the filing is a quote investigators say Munster gave to customs officers. He reportedly said, “all the documents on my laptop, but you don’t need them, I do this all the time.” The FBI later described those statements as “materially false.”
Marcus Sykes of the Office of Inspector General at the Department of Health and Human Services did not soften the language in his statement. He said, “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,”
The National Institutes of Health, which is Munster and Kwe’s home agency, responded by calling the matter “an ongoing investigation and personnel matter.” The agency also said it is cooperating with law enforcement. That is the standard Washington answer when a bad headline lands close to home, but it does little to calm concerns about how closely dangerous materials are tracked.
Munster and Kwe are both experienced virologists who have studied mpox extensively. Still, the federal documents do not explain why they felt the need to bring the vials back to the United States or why they skipped the normal reporting process. The complaint leaves those questions open.
The trip itself adds another layer to the story. The Republic of Congo has seen significant mpox outbreaks, and federal officials have been warning for years about the need for careful handling of biological material, even when it has been inactivated. A move like this, especially through a major U.S. airport, is bound to raise eyebrows.
The case also lands at a sensitive time for public trust in scientific institutions. Americans have been through enough virus-related chaos to know that sloppy handling and weak oversight are not small problems. When researchers working in secure federal labs are accused of dodging customs rules and giving false answers, people notice.
Both men are expected to appear in federal court in Missoula, Montana.
