Per year, thousands and thousands of people go mysteriously missing. Some were identified and returned to their loved ones. Some actually died without leaving some sign of their whereabouts at all.

And, it’s not just the average guy. Even famous celebrities have mysteriously vanished from the face of the planet, never to be discovered.

Neither the plane nor even the two aboard have ever been found. A court order ruled her officially dead in January 1939, 18 months after her absence.

In pursuit of extra-ordinary pictures, he gave up on acting and traveled to conflict areas and his team. Flynn and his colleague received a tip about a Viet Cong highway intersection in April 1970, so they got to travel to the intersection on their motorcycles and try it out for themselves, and that was it. No one has ever seen them or talked from them again, ever. In 1984, at the insistence of his mother, Lili, Flynn was pronounced dead.

In 2005, he needed a sabbatical from acting and went back to his home to finish high school and then decided to go back to LA to seek a career as an actor. He worked at TeleTech back in his hometown as a telecommunications technician.

He appeared to be floating in the sea near Portsea, Victoria. However, sadly, he never returned. A significant search effort was carried out, but there were no leads. He is thought to have either been washed into the water or destroyed by a shark attack, but little can be known for sure. After his disappearance, a slang term was invented, “do a Harry Holt,” which means to suddenly bolt or vanish.

The well-known Swedish director, screenwriter, and producer were Daniel Lind Lagerlof. He vanished in October 2011 during filming and was never reported again.

Daniel Lind Lagerlof

One of the most successful directors was recognized as Lagerlof. He started his TV career as an assistant, and in 1990 he guided his first script, Föreställningen (The Performance). And, among others, he was accredited with directing many blockbusters, such as Beck and Johan Falk, Breaking Out, Making Babies, and Miffo. All was going well for him in his career, but he abruptly vanished on October 6, 2011, without a trace. Lagerlof was in the way of finalizing a filming location for his forthcoming film based on the books of Swedish author Camilla Lackberg, The Tjurpannan Nature Reserve, at the moment of his vanishing.

It is suspected that as he tried to finalize the position for the shooting, he stumbled on some stones and was washed into the water. However, there were no witnesses to support this hypothesis. He was reportedly declared dead in 2016.

In July 1955, Weldon Kees, one of the most famous and influential writers of the 20th century, died, leaving no trace.

He was scheduled to return home after seeing his parents on July 17, 1955, but he never left. On July 19, his car was discovered with the key still on fire. According to his friends and relatives, he was behaving oddly and was increasingly troubled, but nothing was clear. He may have suffered from suicide, it is thought, but his body has never been identified.

Today, all that’s left is crazy stories of conspiracy and uncertainty.
