Tucson is a vibrant, growing city, but beneath the sunny surface lies a dark history. Eva Dugan was convicted of murder and hanged here, the first woman to be executed in the state of Arizona. Gangsters like Joe Bonanno and bank robber John Dillinger were drawn to this corner of the Southwest, and it was home to killers like Robert John Bardo and Charles Schmid, a serial killer nicknamed the "Pied Piper of Tucson." In 1892, William Elliott, stabbed by a notorious criminal, became the first Tucson police officer to lay down his life in pursuit of justice, but he wouldn't be the last. Join author Patrick Whitehurst as he delves into the chilling history of Tucson.
