”....But there are some extraordinary cases of sleep walkers
leaving their homes, driving cars, or engaging in behaviours that
they would not usually. In 1987, Ken Parks, drove 23 kilometres
from his home in Pickering, Ontario, to his in-laws house, where he
strangled his father-in-law unconscious, and stabbed his
mother-in-law to death. He was acquitted of murder because he was
sleepwalking at the time.”
