After an exhaustive investigation, authorities haven’t found anything that would have caused the mass sickness experienced at the Tulsa jail last week. Sheriff’s Sargeant Shannon Clark says no evidence of chemical or carbon monoxide poisoning has been discovered to explain what caused nearly 40 people…most of them students on a field trip…to be treated for nausea.
Clark says some psychologists believe a combination of the heat, the stressful situation, and panic could have led to a kind of psychosomatic mass hysteria that affected many of the victims. In the absence of any physical cause, he says that’s one possible explanation.
