An obituary said that lawyer Douglas Preston was “ranked as the first criminal attorney of Wyoming.” And he certainly gained notoriety as the man who represented outlaw Butch Cassidy in many of his cases, nearly obtaining an amnesty agreement with state officials. But Preston was much more than just a criminal attorney.
He was a member of the Wyoming constitutional convention in 1889. From 1903 to 1905, Preston was in the state house of representatives. And later, he was appointed Wyoming attorney general. Butch Cassidy apparently knew how to pick his lawyers.
