Photos: Power Brothers shootout east of Tucson in 1918
John and Tom Power and Tom Sisson were convicted of murdering the Graham County Sheriff Frank McBride and two deputies in 1918 near Klondyke in the Galiuro Mountains east of Tucson. The group was trying to arrest the brothers for draft evasion during World War I. A federal marshal was wounded.
McBride was known to strictly uphold the law, according to Arizona State University. The Power brothers were wanted for draft evasion – a misdemeanor. Despite this, McBride obtained federal warrants for their arrest and organized a posse.
The Power brothers claim the lawmen never identified themselves when they approached the Power home. The only lawman to survive the shootout was behind the house and not in a good spot to see what ensued.
The three fugitives evaded several posses for nearly a month but were captured by the U.S. Calvary.
The brothers were paroled from Arizona State Prison in 1960 and pardoned in 1969. Tom died in 1970. John died in 1976. Sisson died in prison.
In 1975, the Power cabin in the Galiuro Mountains was placed on the National Register of Historic Places.
