As noted by The New York Times, there are people close to Robert Vesco who believe that he might have tried to evade justice again by faking his death. In an article by The Guardian, the outlet detailed how Nicaragua offered Vesco refuge, similar to how other nations such as the Bahamas, Antigua, and Cuba admired Vesco for the potential that he could bring wealth to their country. Nicaragua went further and gave him a false name, "Tom Adams," for him to use safely; this could only be one of the aliases Vesco used. If the conman lived off a fake name once, who knows how many other times he did and if perhaps he's still doing it?
He was able to lie low when he went to Costa Rica. According to The New York Times, he blended in by investing in a number of tech-related ventures and by working as a dairy and cattle rancher in the Central American country.
With a reputation such as his, there's a chance Robert Vesco, if he is still alive, would be extremely proud to have a character based on him on TV, especially on a show as well enjoyed as NBC's "The Blacklist."
