Investigators discover plot to murder Sheriff Joe Arpaio

Sheriff Joe Arpaio is a controversial figure known nationwide for his tough stance against illegal immigration. Now, authorities have uncovered a plot to kill him, and a Douglas rancher is one of the investigative leads. The investigation began in Yuma when police were tipped off by a confidential source, whom they trust, that someone was out to get Sheriff Joe. Following that lead, authorities began to unravel a plan that stretched deep into Mexico and to a well-known drug cartel that many fear. According to documents, authorities have three investigative leads: Miguel Escalante, the head of a Mexican drug cartel, Elias Bermudez, host of a radio show and an immigration rights advocate, and Roger Barnett, a Douglas rancher. A confidential source tipped off Yuma police that Mexican hitmen known as Los Zetas were "hired by Mexican drug czar Hector Escalante to cross into the U.S. and kill Sheriff Arpaio."....
