On September 19, 1876, Bill Cox and several men shot to death Dr. Phillip Brassell and his son George near Yorktown, Texas. The incident was tied to the Sutton-Taylor Feud. Cox and the others got away with the murders.
A few years later, Cox moved to New Mexico. He reinvented himself as W.W. Cox, a successful rancher, businessman and civic leader. But some things didn’t change. Cox was implicated in the 1896 murders of Albert Jennings Fountain and his son. He was also tied to the assassination of Pat Garrett in 1908.
