"Dangerous Dan" Tucker

(Wikipedia) Dan Tucker, better known as "Dangerous Dan" Tucker, (1849 – unknown), is a little-known lawman and gunfighter of the Old West.
Author Bob Alexander, who wrote the biography Dangerous Dan" Tucker, New Mexico's Deadly Lawman, proclaimed Tucker was more dangerous and more effective than better known lawmen, including Wild Bill Hickock and Wyatt Earp. He was supported in this claim by historian Leon C. Metz. He was also a subject in the book Deadly Dozen, by author Robert K. DeArment, who included Tucker as one of the twelve most underrated gunmen of the Old West.
Tucker first ventured into New Mexico Territory in the early 1870s. Continued
