In 1987, a Canadian man named Kenneth Parks drove 14 miles to the home of his in-laws. Upon reaching their home, Parks brutally attacked them both, killing his mother-in-law. When the case went to trial, he was acquitted on unprecedented grounds: The attacker was asleep. Carlos Schenck, a sleep clinician and author, describes the case and Parks’ history of parasomnias—severe sleep behaviors. He explains that a “witch’s brew” of sleepwalking risk factors could have precipitated the tragic episode.
