It’s a heartbreaking feeling when you lose someone you love or someone close to you. What’s more heartbreaking (and a lot creepier) is when someone suddenly disappears and is never found again. Thousands of people go missing around the world every year. Some of them may have been victims of murder, while others may have just ran away to start their life over. Some missing people are even presumed to have been abducted by extraterrestrials. Whatever the case, here are 10 mysterious and unexplained disappearances throughout history that have captured the imagination of countless conspiracy theorists.

The American singer/songwriter who was active in the 50’s New York scene. She had written letters to her trusted friends about her dissatisfaction with her current life. Connie decided to pack her things into her trusted Volkswagen Beetle, drove off and was never heard of again. Some say she probably changed her name and started a new life somewhere else.

2. Harold Holt

Many people disappear without any explanation but it is rare that a head of state, specifically a prime minister, would just go missing without any concrete explanation. Australian Prime Minister Harold Holt went missing one Sunday morning when he went for a swim in December 1967. A massive search and rescue operation took place but the body of the prime minister was never found. Many rumors surrounding the unexplained disappearance travelled around, including a possible suicide or a faked death to run away with a mistress. Conspiracy theorists say that he may have been kidnapped by a Chinese submarine, or possibly abducted by a UFO. Although these outlandish explanations were being thrown around in the media, it is known that the prime minister was not in good health at the time. It is possible that he may have drowned due to strong beach currents or was attacked by sharks and possibly eaten by these marine carnivores.

3. Forth Worth Three

9 year old Julie Ann Mosely, 14 year old Lisa Renee Wilson and 17 year old Rachel Arnold Trlica went to shop for Christmas presents at the Seminary South Shopping Center in Forth Worth, Texas. The 3 girls never returned home. Their locked car was discovered at the mall parking lot at 6:00 pm with their presents still inside, indicating the girls had finished shopping and had returned to their car at some point. A day after the disappearance, the family of Rachel Trlica received a letter claiming that the three girls had taken off to Houston for a week and would be back. The family doubted that the letter was authentic and none of the three girls ever returned. Over the years of the investigation, some eyewitnesses claimed that the girls were forcibly taken by unidentified males into a van and a witness claimed that he saw the three girls in a security guard’s truck at 11:30 pm. The disappearance remains a mystery to this day.

4. The Flannan Lighthouse Disappearance

On the Outer Hebrides of Scotland, three lighthouse keepers mysteriously disappeared from the island. Some people speculated that three men might have been blown away by strong winds, landed on water and then drowned due to strong currents. Some of the remaining men on the island gathered every possible clue in order to solve the disappearance of the three lighthouse men. According to the investigation, the east landing was very intact but the west landing has seen serious damage due to recent storms. However, a log was discovered showing that the three men had recorded their time worked until 9am on the 15th of December, proving that the damage happened before the mysterious disappearance.

5. Lt. Felix Moncla And 2nd Lt. Robert Wilson

In 1953, Air Force Lt. Felix Moncla was assigned at the Michigan Kinross Air Force Base. A UFO was intercepted by radar and Lt. Moncla was ordered to intercept and investigate in his F-89 Scorpion. Ground radar stated that Moncla’s fighter jet flew about 500mph and closed in on the UFO while crossing the Northern Lake Superior from west to east at an altitude of 7,000 feet. Radar operators claimed that what they saw on radar was truly bizarre. The fighter jet and the UFO merged and disappeared, based on radar intercepts. A search and rescue took place but no debris or wreckage of either aircraft could be found. Lt. Moncla and his aircraft were never seen again.

6. Amelia Earhart

In 1937, pioneer aviator, author, teacher, fashion designer and magazine editor Amelia Earhart was just 39 years old when she and her navigator Fred Noonan disappeared during their attempt to circumnavigate the world flying their Lockheed Electra 10E plane. The plane vanished in the Pacific Ocean on July 22, 1937 while they were enroute to Howland Island from New Guinea. Authorities have stated it was most likely that the duo got lost, ran out of fuel and crashed into the sea. Some say that the two aviators were captured by the Japanese because they were on a secret spying mission from President Roosevelt. Others say they were able to survive on an island and made their way to the United States and assumed different identities. During the 70’s people claimed to have seen Amelia under a different name, Irene Craigmile Bolam.

7. Agatha Christie

The famous British crime novelist married to Archie Christie. Their marriage was on the rocks because of her husband’s infidelity. Archie admitted that he was in love with his mistress Nancy Neele and wanted to get a divorce. On December 3, 1942, the couple had a heated argument and Archie left their house to be with his mistress in Godalming, Surrey. That same evening, Agatha left their house with a note to her secretary that she would be leaving for Yorkshire. She was not found or heard from for 11 days, even though a massive search was ordered. On December 14, 1926 she was identified as a guest in the Swan Hydropathic Hotel, registered under the name of Mrs Teresa Neele from Cape Town. She never gave any explanation about her disappearance. Two doctors diagnosed Christie with a rare Psychiatric disorder known as reversible amnesia. Some people say the episode occured due to her severe depression and her husband’s infidelity, while some say that she wanted to frame her husband for her disappearance. Agatha Christie died on January 26, 1976.

8. Frederick Valentich

In 1978, while Frederick Valentich flew his Cessna 182L light aircraft, he reported an encounter with a UFO on his way to King Island, Australia. He claimed that the UFO flew 1,000 feet above him and hovered on top of his aircraft. Soon after his contact with radar operators, his plane malfunctioned and completely disappeared from radar. He was never found again. Despite the efforts to debunk the UFO angle, the last 17 seconds of the flight recording contain unexplained metallic noises. The Department of Transport’s Aircraft Accident Investigation have a transcript of the communication between Valentich and the Melbourne Flight Services at the time of the incident. There were also claimed reports of UFO sightings on the same weekend and a few years later, a man claimed that he had artifacts containing compelling messages from Valentich during his supposed alien abduction. Nothing came of the proposed evidence.

9. Jimmy Hoffa

Don’t mess with the Italian mob! Union leader Jimmy Hoffa is one man that crossed a thin line between being a Union leader and appeasing the Mafioso who offered protection and funneled illegal funds into his organisation, the International Brotherhood of Teamsters. Jimmy Hoffa was a corrupt man who tested the patience of the mob when he tried to regain control of teamsters. Hoffa was last seen in a Michigan restaurant in 1975 where he was scheduled to meet with two capo regimes Anthony Giacalone and Anthony Provenzano. The majority opinion says this was a classic mob hit.

10. Glenn Miller

Popular bandleader and jazz man Genn Miller vanished when he was en route from England to France, where he was scheduled to do a performance for the allied troops in the recently liberated Paris. News of his disappearance did not circulate very fast because it was overshadowed by the last German offense and the allied victory in the Battle of The Bulge, which pushed the story to the back pages of many newspapers. No one knew what happened to the plane he was on. Some say it might have been hit by a German fighter plane or his plane was hit by ordnance being dropped by British bomber planes when going back to England. Whatever the reason, it was one of the most heartbreaking disappearances and a huge loss to the American music scene.

These disappearances are disturbing, mind-boggling and somewhat creepy. May the families of these lost souls be in peace.
