In addition to conducting extensive archival research, Vanderwood interviewed central actors in the events of 1938, including Olga Camacho's mother, citizens who rioted to demand Morales's release to a lynch mob, those who witnessed his execution, and some of the earliest believers in his miraculous powers. Vanderwood also interviewed many present-day visitors to the shrine at Morales's grave. He describes them, their petitions-for favors such as health, a good marriage, or safe passage into the United States-and how they reconcile their belief in Juan Soldado with their Catholicism. Vanderwood puts the events of 1938 within the context of Depression-era Tijuana and he locates people's devotion, then and now, within the history of extra-institutional religious activity. In Juan Soldado, a gripping true-crime mystery opens up into a much larger and more elusive mystery of faith and belief.
