Willard Christianson, outlaw.
Willard Erastus Christianson (aka Christiansen), who was also known as Matt Warner, Ras Lewis, and the Mormon Kid, was both an outlaw and a lawman who operated primarily in Utah and Washington.
Christianson was born in Ephraim, Utah, in 1864 to a Danish father and a German mother who had come to Utah as converts to the Mormon Church. Though his start was good, he got into a fight when he was 14 years old, and fearing he had beaten the other boy to death, he ran away. He soon joined a band of rustlers to begin his life as an outlaw. At this time, he began going by the name of Matt Warner.

Somewhere along the line, he married a girl named Rose Morgan, and the two ran a cattle ranch in Big Bend, Washington, before returning with his wife and a daughter to Utah. He then hooked up with his brother-in-law, outlaw Tom McCarty, operating in the Robbers Roost area of Southeastern Utah.
In no time, Warner was robbing banks and trains with the likes of Elza Lay and Butch Cassidy. He then got into a shootout in 1896, where two men were killed. He was convicted of manslaughter, earning him five years in the Utah State Prison. Though he received an early release for good behavior, his wife died during his incarceration.
In 1892, Christianson, along with Bill and Tom McCarty, robbed a bank in Roslyn, Washington, and when bystanders attempted to stop them, two men were shot and wounded. Later that year, Christianson was apprehended and tried in Ellensburg, Washington, for the bank robbery. However, he escaped two days before his trial.

At some point, he remarried and settled in Carbon County, Utah. Warner ran for public office under his real name, Willard Erastus Christianson, and lost. He then had his name officially changed to Matt Warner, the name most people knew him by. He was elected justice of the peace and then served as a deputy sheriff. Later, he worked as a night guard and detective in Price, Utah. At other times, he worked as a farmer, cowboy, rancher, ferryman, and bootlegger.
He died a natural death on December 21, 1938, at the age of 74.
