According to a 1939 article in TIME magazine, one of the shamans was with the Medina family when they finally took the girl to hospital in Pisco, Peru. And apparently, the female shaman begged a Dr. Geraldo Lozada, one of the hospital’s surgeons, to “exorcise” the “possessed” girl himself.
Clearly, though, a medical professional like Dr. Lozada was not going to do such a thing. Instead, he did what any regular doctor would do and gave the girl an examination. Yet what he discovered would surely have come as a complete shock.
