Luke Denman, 34, was one of two ex-Green Berets arrested in a foiled plot to oust Venezuela's President Nicolas Maduro. He's now locked up in a Venezuelan jail, his fate in the hands of a leader the U.S. government considers a dictator responsible for tens of millions of his people going hungry. Much remains unknown about the ill-fated operation. According to the Venezuelan government, eight "mercenary terrorists" were killed and several captured, including Denman and fellow Army veteran Airan Berry, during an attempt to seize Maduro and topple his government. A third ex-Green Beret, Jordan Goudreau, claimed responsibility for the plot. A decorated former U.S. commando, Goudreau operated a Florida-based private security company called Silvercorp USA. Before he went into hiding, Goudreau had said in multiple interviews the plan was initially coordinated with representatives of Venezuelan opposition leader Juan Guaido, who is recognized as the country's interim president by the U.S. and much of the international community. But the relationship soured and Goudreau moved forward with the operation anyway. In interviews with NBC News, a half dozen family members and close friends of Denman and Berry said they believe the former Special Operations soldiers would have only participated in such an operation had the two men been convinced it was supported by the U.S. government.
