Gale Cooper, a Harvard Medical School educated M.D. forensic psychiatrist, draws on her 20 years of Billy the Kid writings and research to write Cold Case Billy the Kid: The Plot to Steal Billy the Kid’s Identity and to Defame Sheriff Pat Garrett as a Murderer. It is the definitive debunking of Billy the Kid imposter hoaxes: old men who claimed to have survived Sheriff Pat Garrett’s famous July 14, 1881 shooting and to have lived to old age, and their profiteering promoting authors. For the first time, in one big book, with meticulous exposes and profuse sources, are included the 20th century pretenders, Oliver Brushy Bill Roberts and John Miller; and their 21st century revivals in the Billy the Kid Case forensic DNA hoax, and the Cold Case Billy the Kid megahoax, which combined them all. Not only are profiteering charlatans debunked; but, in contrast, the art, science, and labor of discovering real history are demonstrated. Additional concerns are voiced about irresponsible promotion of the antiquated pretenders and their false conspiracy theories in documentaries hawking history’s mysteries and victimizing their unsuspecting audience.
