Kevin Costner is teaming with National Geographic to explore the legend of Billy the Kid — specifically a mysterious photo believed to only be the second one of the famed outlaw.
The special, Billy the Kid: New Evidence, will premiere Sunday, Oct. 18 at 9 p.m. and trace the origins of a newly discovered tintype containing what appears to be a second image of the famed fugitive. Only one photo of William H. Bonney — better known as Billy the Kid — exists.
