Maybe Butch Cassidy Wasn't Killed in Bolivia

As Carlos Pero encouraged his mule to lumber up a rugged trail high in the Andes Mountains on the morning of November 4, 1908, little did the courier for the Aramayo, Francke and Cia mining company realize that his every move was being watched. Pero later recounted that after cresting a hill, he was “surprised by two Yankees, whose faces were covered with bandanas and whose rifles were cocked and ready to fire.” The pair of masked bandits robbed the courier of the company's payroll and then disappeared into the cacti-dotted desolation of southern Bolivia.
