With his brother imprisoned in
Nebraska, John Sontag came to
Fresno, California, and began working for the
Southern Pacific Transportation Company. After an industrial accident, he was employed near
Visalia, California, by a farmer and
livery stable operator, who soon became his partner in crime,
Christopher "Chris" Evans. After Contant was released from prison in Lincoln, he joined his brother in a train robbery near
Racine, Wisconsin, on November 12, 1891, that was very successful. He then joined Chris Evans on a trip to Minnesota, where on July 1, 1892, they attempted to rob a train while riding along the
Minnesota River between
St. Peter and
Kasota. They acquired nothing of much value, but their crime aroused the concern of
Pinkerton detectives. Found guilty of train robbery at Collis in October 1892, Contant was incarcerated for fifteen years at
Folsom State Prison. The following June 1893, John Sontag died shortly after his 32nd birthday either of gunshot wounds sustained at the
Battle of Stone Corral and/or
tetanus while in custody in Fresno. Chris Evans lost an eye and his left arm preceding his surrender. He too was sent to Folsom, where he remained for seventeen years . George Contant tried to escape in 1893. ==After prison==
