Lady Lucan, the 80-year-old widow of Lord Lucan, was found dead at her home in London, the one from which her husband famously disappeared more than four decades ago, reports said Tuesday.

Police officers forced entry into the residence of Veronica, the Dowager Countess of Lucan, in Belgravia in Westminster on Tuesday afternoon after she had been reported missing, and found her unresponsive.

A spokesman for the Metropolitan Police (Met) said: "Police attended an address on Eaton Row in Westminster ... following concerns for the welfare of an elderly occupant.”

"Officers forced entry and found an 80-year-old woman unresponsive. Police and London Ambulance Service attended. Although we await formal identification we are confident that the deceased is Lady Lucan,” the spokesman said, the Independent reported.

Police said her death was not believed to be suspicious, but it is still unexplained.

Her son George Bingham, the 8th Earl Lucan, said she passed away alone and "apparently peacefully" at home.

He told the Daily Mail on Tuesday night: "Police were alerted by a companion to a three-day absence and made entry today."

Lady Lucan was said to be one of the last persons to see Lord Lucan alive before he famously vanished in 1974, after the body of the family's nanny Sandra Rivett was found at the family residence on Nov. 7 1974, BBC News reported.

Lord Lucan’s car was later found abandoned and covered in blood in Newhaven, East Sussex. Despite being declared dead by the High Court in 1999, he has reportedly been sighted in New Zealand, Australia, Ireland and South Africa. There were even claims that he reportedly fled to India and lived a life of a hippy named “Jungly Barry.”

The night as Lord Lucan’s disappearance, it was said that he also turned on his wife, allegedly beating her severely before she escaped and raised an alarm at a nearby pub.

The head barman of Plumbers Arms, Derrick Whitehouse, told Roger Bray, who was the first journalist to report the case involving Lord Lucan, that Lady Lucan “staggered” in and said: "I think my neck has been broken. He tried to strangle me."

The barman said Lady Lucan was "just in a delirious state," telling Bray: "She just said 'I'm dying.' She kept going on about the children. 'My children, my children,' she said. She came staggering in through the door and I gave her all the assistance I possibly could. I've only seen her in here once before," the Independent reported.

Lady Lucan said earlier this year that she believed her husband took the “brave” decision to take his own life.

In an hour-long documentary called “Lord Lucan: My Husband, The Truth,” she explained: “I would say he got on the ferry and jumped off in the middle of the Channel in the way of the propellers so that his remains wouldn’t be found – I think quite brave.”

Lady Lucan met her husband John Bingham in early 1963 at a golf function, then got engaged in October and eventually got married in November of that year, Mirror.co.uk reported.
