Three cases are outlined where a person commits murder and then blames the crime on sleepwalking.
First up, Albert Tirrell murders his mistress in 1846 claiming he was in a trance-like state at the time. Kenneth Parks travels 23 km to commit a murder - all while asleep, he claimed. Finally, another man tries to use the sleepwalking defense after killing his wife in Phoenix, Arizona in 1997.
