"When Wes was two years old he learned how to handle guns as a hunter and by shooting at effigies of Abraham Lincoln during the Civil War."

"At fifteen he shot a former slave to death. Soon thereafter he ambushed and killed three soldiers who intended to arrest him."

"The next year Wes worked in a cow camp near Corsicana, the county seat, where he became acquainted with another young fugitive, Bill Langley."

"Wes soon drifted to tiny Towash, where he killed another man. He then fled to an uncle's farm near Brenham, becoming involved in two more shootings along the way."

"He worked as a cowhand for a while, gambled, took part in a shooting scrape, and finally went up the Chrisholm Trail with a herd for Abilene, killing an Indian in Indian Territory to keep in practice."

"After hunting down an Mexican killer in Kansas, Wes returned to Smiley, where he had another shootout with lawmen. He escaped to marry Jane Cowen."

"After his marriage, Wes soon engaged in three more shootings. Wes remained relatively inactive for about a year, but he killed Deputy Sheriff Charles Webb in 1874."

I got this information from the book Encyclopedia of Western Gunfights. This book was published in 1979 at the University of Oklahoma by Bill O' Neal.
