As a result, other works by Boyer were subsequently questioned. His book, "Wyatt Earp's Tombstone Vendetta", published in 1993, was according to Boyer based on an account written by a previously unknown Tombstone journalist that he named "Theodore Ten Eyck", but whose identity could not be independently verified. Boyer claimed that the manuscript was "clearly authentic" and that it contained "fascinating revelations (if they are true) and would make an ace movie". Boyer later said the character was in fact a blend of "scores of accounts", but could not provide any sources.
