John Bingham, 7th Earl of Lucan (b. 18 December 1934), known as Lord Lucan, disappeared without trace in 1974. Born in Marylebone, he attended Eton College and served with the Coldstream Guards, later becoming a professional gambler. Lucan had expensive tastes; he raced power boats and drove an Aston Martin. In 1963 he married Veronica Duncan, with whom he had three children, but the marriage collapsed in 1972 and he moved out of the family home in Belgravia. He lost a bitter custody battle, began to spy on his wife and children, and incurred gambling losses. In November 1974 the children's nanny, Sandra Rivett, was murdered in the basement of the Lucan family home. Lady Lucan was also attacked and she identified Lucan as her assailant. As the police investigated, Lucan drove to a friend's house in East Sussex; hours later, he left and was never seen again. The car was found with a blood-stained interior and a lead pipe similar to one found at the crime scene in its boot. A warrant for his arrest was issued, but despite hundreds of reported sightings, he has not been found and as of 2016 is legally presumed dead.
