Over the years, people have disappeared and are never seen again. Stranger yet, their disappearance may remain a secret until that person is forgotten completely. One of the strangest disappearances took place in the year 1974.

In November, a 39-year-old aristocrat known as Lord Lucan vanished. He had left behind the bloody, gruesome mess of his children’s nanny, Sandra Rivett. Apparently, he mistakenly killed the nanny, thinking she was his wife.

The most successful detectives from Scotland Yard still had no idea where Lucan went; the mystery is still talked about today. With the body of Lucan still not found comes the countless conspiracy theories as to what may have happened to him.

Lord Lucan standing outside with his future wife, Veronica Duncan, 14 October 1963. Many believe he skipped the country and lived abroad undercover for the rest of his life. Even today, there have been many sightings of Richard John Bingham, the 7th Earl of Lucan, reported around the world.
