Knowledge is Power


The world can be a dark place. Sometimes, events are so odd that no one can figure out exactly what happened. Missing people, murders, secret societies, and even potential paranormal events have confused people for years.

Here are some of the facts we do know about these unsolved mysteries.

43. Elisa Lam

On January 31, 2013, 21-year old Canadian Elisa Lam was on vacation at the Hotel Cecil in Los Angeles. Security cameras captured her on the elevator. In the video, she looked scared of someone–or something. She left the elevator, acting very strange…and disappeared. Weeks later, her body was found in the water tower on the top of the hotel. The Los Angeles Police department claimed her death was “accidental drowning”, but internet sleuths think that something more may be going on.

42. Cicada 3301

A strange image appeared on the website 4Chan in 2012. The anonymous poster claimed that they were from a secret group called Cicada 3301, and they are looking for intelligent people to join their organization. There was a secret message hidden in an image. This clue lead to dozens of other puzzles, which eventually showed that the group exists all over the world. No one is sure who or what Cicada 3301 actually is, but new puzzles appear in January of every year.

41. The Mary Celeste

In 1867, a beautiful ship named the Mary Celeste left the coast of New York. The captain was a man named Benjamin Briggs, and he brought his family and crew to transport 1,700 barrels of alcohol to Italy. They never made it to their destination. The boat was found floating safely in the Atlantic Ocean, off the Azores Islands, on December 5, 1872. This did not look like a pirate attack, because nothing was stolen, and all of the paper documents were still on board. The only thing missing was the people.

40. James McGrogan

In 2014, a doctor named James McGrogan went on a winter hiking trip using split snowboards on the snowy trails of Vail, Colorado. He brought his fully charged cell phone, a GPS, and survival gear–not to mention two friends to hike with. James was athletic, so he got farther ahead on the trail. His friends could not find him. Despite the fact that there was snow on the ground, no one could find any sign of James’ tracks. A week later, James’ body was found… but he would have had to climb several mountains and many miles to get there. When the rescue team found his body, they discovered that his phone still worked and he should have been able to call for help.

39. The Taos Hum

In a small town of Taos, New Mexico, there is no such thing as silence for some people. When townspeople quiet down, many citizens report they can hear a humming noise, similar to a diesel engine. In 1997, Congress decided to investigate the hum, and yet they could not come up with a rational explanation. The sound is undetectable by audio equipement.

38. The Zodiac Killer

A serial killer nicknamed “The Zodiac” killed at least 5 people in California during the 1960’s.

All of the victims were shot, and the police would have never connected the dots, if he had not called them, admitting his crimes. He explained that he enjoyed “hunting” people. He has still never been caught.
