Black Jack Christian, aka 202, or Ed Williams, (September 5, 1871 – April 28, 1897) was an outlaw of the Old West.

[1] Black Jack was documented in reports of outlaw activity in the late 1880s, along with his brother Bob Christian.

During this time of the late 1880s and early 1890s, he and his brother Bob organized the "High Fives Gang", operating mostly around New Mexico Territory.

[3] The following year, with the help of a wealthy rancher associate, on August 6, 1896, the gang robbed the "International Bank" in Nogales, Arizona.

While approaching Skeleton Canyon, they were fired upon by some of the High Fives, immediately killing Special Deputy Frank Robson, who was riding in front.
