The Sleepwalker Killing also known as From the Files of Unsolved Mysteries: The Sleepwalker Killing, is a 1997 TV movie based on a popular real-life case from the Unsolved Mysteries television series. The film was written by June Callwood and Lyle Slack and directed by John Cosgrove. Cosgrove also served as executive producer on the TV series.
Plot
A segment from the Unsolved Mysteries TV series inspired this story, in which Mark Schall kills his mother-in-law and wounds his father-in-law in the middle of the night, then turns himself in. He claims, however, that he cannot remember the crime itself. His defense team finds evidence that suggests the crimes were committed while Mark was sleep walking. They build their defense around this theory.[1]
