Federal investigators say they found the DNA of a decorated former U.S. Green Beret on some of the 60 automatic weapons he allegedly smuggled from Florida to South America as part of a failed 2020 coup attempt against Venezuelan President Nicolás Maduro.

The plot, exposed by The Associated Press two days before the incursion, was carried out by a ragtag group of Venezuelan army deserters whom Goudreau allegedly helped arm and train in neighboring Colombia. Goudreau later claimed responsibility for the putsch, but said he was acting in concert with the Venezuelan opposition to protect democracy. He also said he was in touch with then-President Donald Trump’s administration, which made no secret of its desire to see Maduro gone, even though there’s no evidence U.S. officials blessed the invasion.
