Mother-of-two Renee MacRae thought she was about to begin a new life with her secret married lover in 1976.

At around 10 p.m. on November 12th, Renee’s blue BMW was found ablaze but she and her three-year-old son Andrew had vanished. Bloodstains on a rug in the boot were said to be a match for the pair.

Now, 46 years after that fateful day, 80-year-old William “Bill” MacDowell is behind bars for their murder.
