psychopharmacology at the movies

"On December 7, 1982, Richard Delmer Boyer of El Monte, California, murdered Francis and Eileen Harbitz, an elderly couple in Fullerton, California, leading to the trial People v. Boyer (1989). The couple were stabbed 43 times by Boyer. According to the trial transcript, Boyer's defense was that he suffered from hallucinations in the Harbitz residence brought on by "the movie Halloween II, which defendant had seen under the influence of PCP, marijuana, and alcohol." The film was played for the jury, and a psychopharmacologist 'pointed out various similarities between its scenes and the visions defendant described.' Boyer was found guilty and sentenced to death."
