Jonathan Luther "John" "Casey" Jones (March 14, 1863 – April 30, 1900) from Jackson, Tennessee, was an American railroader who worked for the Illinois Central Railroad (IC). As a boy, he lived near Cayce, Kentucky, where he acquired the nickname of "Cayce," which he chose to spell as "Casey." On April 30, 1900, he was killed when his passenger train, the Cannonball Express, collided with a stalled freight train at Vaughan, Mississippi, on a foggy and rainy night.

Arnold Bernid "Casey" Jones is a fictional character from the Teenage Mutant Ninja Turtles comics and all related media. Like the turtles, Casey Jones is a vigilante, and was created as a parody of vigilante characters that were in comics. Casey sometimes has long, dark hair, wears a hockey mask and sometimes cut-off biking gloves, and sometimes carries his weapons in a golf bag over his shoulder.
