Robert Francis Mone (born 1948) is a Scottish murderer who was sentenced to life imprisonment in 1977. In 1967 he shot a teacher at his old school, and in 1976 he and another man escaped from the State Hospital, Carstairs, killing three people in the process. He is Scotland's longest-serving prisoner. Early life Mone was born in Dundee and grew up with his parents and two sisters. He was bullied by his father and claims to have been raped by a family friend when he was 12. He became depressed when his grandfather died and lived with his grandmother for a while. In 1964, he was expelled from St John's High School. He then joined the Gordon Highlanders and served in the British Army of the Rhine in Germany. Murder of Nanette Hanson On 1 November 1967 Mone, who was absent without leave from his army unit, and had been drinking for days, entered a girls' needlework class at St John's wearing his uniform and armed with a shotgun. He held the 14- and 15-year-old pupils and their pregnant teacher, Nanette Hanson, captive for 90 minutes. He requested that an acquaintance - 18-year-old nurse Marion Young - be brought to the school. During the standoff, Mone raped one girl, sexually assaulted another, and shot at both women, but the gun misfired. Police brought Mone's grandmother who unsuccessfully asked him to stop. In 2017 a retired police officer claimed that a police sniper had Mone in his sights but was denied permission to shoot. Young and Hanson persuaded Mone to release the girls, but before giving himself up he shot Hanson in the back. She later died in hospital. On 23 January 1968 Mone was found to be insane and sent to the State Hospital in Carstairs. Young was awarded the George Medal and Hanson was posthumously awarded the Albert Medal. Mone's motive is assumed to be revenge for his expulsion from the school. Escape from Carstairs On 30 November 1976, Mone broke out of Carstairs with his lover and fellow patient Thomas McCulloch, who had shot and wounded two employees at a restaurant in a dispute about getting too little butter for his roll. The two had planned the escape for six months and had assembled a rope ladder, weapons, fake ID and cash. They killed another patient, Ian Simpson, and a nursing officer, Neil McLellan, then climbed a barbed
