Doctor Emmett Brown's tombstone became a reality after he was shot in the back by Buford Tannen on September 5, 1885 over a matter of eighty dollars, seventy-five dollars of which involved Tannen's stolen horse that threw a shoe — and which Tannen subsequently shot, forcing him to steal another — and the remaining five dollars for a bottle of fine Kentucky Red Eye whiskey which got smashed in Tannen's fall from his steed. The tombstone was erected in memory by his love Clara Clayton who took care of him for two days while the bullet that entered Doc killed him slowly. After he died on September 7, he was placed in Boot Hill Cemetery, and the tombstone was engraved with ERECTED IN ETERNAL MEMORY BY HIS BELOVED CLARA.
