S04:E08 - Accident or Murder?

In 1989, Nova Scotia schoolteacher Clayton Johnson left for work. Later that morning, Mrs. Molloy arrived to drop off her child at the Johnson home. She found Clayton's wife Janice Johnson lying at the bottom of the basement stairs in a pool of blood and it was determined to be an accident. Later on, Clayton Johnson married a 22-year-old member of his Pentecostal congregation. When homicide investigator Brian Oldford heard this, he became suspicious and decided to reinvestigate.
