Where's Dan Bogan?

Have you seen this man?

(Wikipedia) Dan Bogan (1860 – after 1889) was an American gunfighter and outlaw of the American Old West, who today is considered to have been one of the most underrated gunmen of the 19th century west.

In his book "A Lonestar Cowboy," published in 1919, Charlie Siringo revealed that he believed Bogan was still living, and that he had reason to believe Bogan had returned to the United States under yet another assumed name, married, settled in southwestern New Mexico, and raised a family on a small ranch. However, he never revealed the identity of who he believed Bogan to be, but suffice to say Siringo felt all but certain he knew these facts.
In some support of Siringo's allegations, former Bogan friend A. C. Campbell stated in 1931 that the last he heard of Bogan, he was alive and well with a family, operating a small ranch under an assumed name in Texas. Continued
