Renee MacRae (born Christina Catherine MacDonald, February 1940) was a Scottish woman who disappeared on 12 November 1976, together with her 3-year-old son Andrew. Their case was the United Kingdom's longest-running missing persons case, and within Scotland is as notorious as Glasgow's Bible John murders. In September 2022, William (Bill) MacDowell was found guilty of the murder of MacRae and her son. Their bodies have never been found. Disappearance Renee MacRae lived in Inverness and was married to Gordon MacRae, though the couple were separated. She had two sons, 9-year-old Gordon and 3-year-old Andrew. On Friday 12 November 1976 MacRae left her home in Cradlehall with both her sons. She dropped elder son Gordon at her estranged husband's house and turned south on to the A9, in the direction of Perth, apparently to visit her sister in Kilmarnock. Neither MacRae nor Andrew have ever been seen again. Later the same night, twelve miles away, a train driver spotted MacRae's burning BMW in an isolated lay-by. When the police reached the vehicle, it was charred and empty apart from a rug stained with blood matching MacRae's blood type. Despite an extensive search, no further trace of Renee and Andrew MacRae was found, and it was concluded that they had been murdered and their bodies hidden. Witnesses on the A9 reported seeing a man dragging something they thought was a dead sheep not far from the car. MacRae was reported to have been wearing a sheepskin coat when she disappeared. Reports also placed a man with a pushchair near Dalmagarry quarry. As police investigated, it became apparent that MacRae's personal life was not straightforward. Around 1971, unbeknownst to her husband, MacRae began to have an affair with William (Bill) MacDowell, who was married with two children and worked for Gordon MacRae as an accountant and company secretary. Nobody knew about the affair except Valerie Steventon, MacRae's best friend. Steventon revealed that MacRae had not been planning to visit her sister that night, but had intended to travel to Perthshire to visit MacDowell, Andrew's biological father. MacRae had first confided to her friend about her conducting an affair in the spring of 1973, when she had been pregnant with Andrew. According to Steventon, "Renee was completely besotted by Bill", and he had told her that he had a job with Texaco in Shetland and had found a house where they could live. According
