On today's episode of A Killer Podcast, Freya tackles the disturbing case of James P. Riva, also known as the 'Schizophrenic Vampire'. In 1980 James committed a terrible crime against his own blood and used his belief that he was a 700-year-old vampire as his defence. The hosts discuss several elements to the case, in particular the topic of the insanity plea and how easy it is to prove someone understands right from wrong during a crime.
