David E. Thompson, United States Ambassador to Mexico, writes to President Roosevelt about his suspicions that Edward Henry Harriman was involved in the Guatemalan revolution of the previous year. Two days before, Thompson met with exiled Guatemalan General Manuel L. Barillas who implicated Harriman in the revolution. The following day, Barillas was assassinated. President Porfirio Díaz of Mexico has told Thompson in confidence that he is certain Barillas was assassinated on orders from Guatemalan President Manuel Estrada Cabrera.
