Train robber John Reno made a big mistake when he got drunk in early 1867.
He and pal Frank Sparks were imbibing in a Seymour, Indiana saloon owned by Dick Winscott. The bar owner asked to take a photo of the boys, and they agreed—assuming a formal pose, with mugs in hand and a dog at their feet.
Reno and Sparks didn’t know Winscott was working with Pinkerton detectives, who got a copy of the photo that finally identified the outlaws. It eventually led to the arrest of both of them (Sparks would be lynched in 1868).
