When an attractive young woman from a privileged British family is murdered in Italy, you’ve got a popular crime story. When the person suspected of killing her is an attractive young woman from a privileged American family, you have tabloid gold. When the prosecutor hypothesizes that the victim was slaughtered during a satanic ritual orgy, you’ve got the crime story of a decade. When a sitting U.S. senator declares that the case “raises serious questions about the Italian justice system” and asks if “anti-Americanism” is to blame, and when 11 Italian lawmakers in Silvio Berlusconi’s coalition request a probe of the prosecutor’s office — well, at that point, you have an international crisis.
