Richard Trenton Chase (May 23, 1950 December 26, 1980) was an American schizophrenic serial killer who killed six people in the span of a month in Sacramento, California. He was nicknamed 'The Vampire of Sacramento' because he drank his victims' blood and cannibalized their remains. A self-described victim of abuse at the hands of his mother, Chase exhibited by the age of 10 evidence of the Macdonald triad: enuresis, pyromania, and zoosadism. In his adolescence, he was known as an alcoholic and a chronic drug abuser. He suffered from erectile dysfunction due to 'psychological problems stemming from repressed anger'. Chase developed hypochondria as he matured. He often complained that his heart would occasionally 'stop beating', or that 'someone had stolen his pulmonary artery'. He would hold oranges on his head, believing Vitamin C would be absorbed by his brain via diffusion.
