Lord Lucan: the disappearance that gripped Britain

In November 1974 nanny Sandra Rivett was killed in London and Lord Lucan vanished. A summary of the case, the inquest and the 2016 death certificate.

On the night of 7 November 1974, Sandra Rivett, the 29-year-old nanny to the children of Richard John Bingham, 7th Earl of Lucan, was killed at the family home in Lower Belgrave Street, Belgravia. Lady Lucan was also attacked and escaped to a nearby pub. Lord Lucan was never seen again.

What happened next?

That night Lucan telephoned his mother and visited friends in Sussex, giving an account in which he had interrupted an attack. A car he had borrowed was later found abandoned in Newhaven, with bloodstains and a piece of lead pipe similar to one found at the house.

The inquest

In June 1975 the inquest jury named Lord Lucan as Sandra Rivett's killer. This was one of the last times an inquest jury in England was able to name a person in this way; the law was changed shortly afterwards.

Declared dead

Lucan was presumed dead by the High Court in 1999 for probate purposes. In February 2016 a death certificate was issued under the Presumption of Death Act 2013, allowing his son to inherit the title.

The sightings

Over the years there were reported sightings in Africa, Australia and elsewhere. None was confirmed. Whether he took his own life soon after that night or escaped abroad is still unknown.

Remembering Sandra Rivett

Coverage of the case has often focused on the aristocrat rather than the victim. Sandra Rivett's family have long asked that she be remembered too.

The night in more detail

Sandra Rivett was attacked in the basement of the house, where she had gone to make tea. Lady Lucan went downstairs to look for her and was attacked on the stairs. She later said her attacker was her husband. She escaped and ran to the Plumbers Arms pub nearby, crying for help.

Police found a heavily bloodstained length of lead pipe, wrapped in tape, in the house. Sandra Rivett's body was in a canvas mailbag.

That night, Lucan drove to the home of friends in Uckfield, East Sussex, and wrote letters, including to his brother-in-law, giving his version of events and referring to his financial affairs. He left in the early hours. The borrowed Ford Corsair was found days later in Newhaven.

The background

Lord and Lady Lucan had separated, and he had lost a bitter custody battle for their children. He was a professional gambler with mounting debts. Police at the time believed the attacker may have mistaken Sandra Rivett for Lady Lucan in the dark: the nanny usually had Thursday nights off, but had changed her night off that week.

Lucan's friends, many from the wealthy gambling set, were criticised for being unhelpful to police, which they denied.

The theories

• Suicide: some believe he took his own life soon after, possibly by jumping from a ferry or in the sea near Newhaven. No body was found.
• Escape abroad: claims that wealthy friends helped him reach Africa or elsewhere have been widely reported but never proved.
• A hired killer: a theory that Lucan hired someone to kill his wife has also been suggested, without proof.

Later developments

Lady Lucan maintained her account until her death in 2017. Over the decades, newspapers reported numerous sightings and claims, none of which led to Lucan being found. No one has ever been tried for Sandra Rivett's murder.

Why it matters?

The case is often told as an aristocratic mystery. At its heart, though, is the killing of a young woman doing her job, and a family left without answers. Her son and other relatives have spoken publicly about wanting her to be remembered by name.
