Although Priven's psychiatrist at his trial testified that he suffered from latent paranoid schizophrenia, a panel of psychiatrists who discussed the murder as a case study in 2005 concluded that Priven was probably suffering from narcissistic personality disorder, which manifests itself as an obsessive involvement with one's own interests and a lack of empathy for others. They further concluded that had Priven been charged in an American court, he would not have been able to mount a successful defense "by reason of insanity."
