U.S. outlaws.
Probably born in Cass Co., Mo., they worked as cowboys in Oklahoma but by 1889 had become horse thieves. In 1890–91 they robbed gambling houses, trains, and banks. In 1892 Bob, Grat, and Emmett Dalton and two other gang members rode into Coffeyville, Kan., to rob its banks; they were recognized, and vigilante citizens killed all but Emmett, who was wounded and sent to prison for 14 years. The fourth brother, Bill, had returned to Oklahoma before the raid; he later formed his own gang, and was shot by lawmen in 1894 while playing with his daughter.
