An unexplained series of lights that have been appearing on Mitchell Flat east of Marfa, Texas for most of the last century, they are described as being the size of a basketball, floating in the air at around shoulder height, and sometimes moving rapidly in various directions. Although sightings are rare there is a large amount of photographic and video evidence. Skeptics, however, usually attribute them to traffic on US Route 67, or electric byproducts of quartz mining in the area.
An American labor leader and criminal, Hoffa disappeared from a parking lot in Detroit shortly after his release from prison. He had been allegedly due to meet up with a couple Mafia leaders but was never heard from again. While the most popular belief is that he was shot and buried in the Giants stadium, when the MythBusters team dug in the part of stadium where Hoffa was supposedly buried they found nothing.
A serial killer that terrorized London’s East End around the turn of the century, his name was taken from a letter he allegedly sent to a local newspaper. The murders were fairly gruesome and typically involved the dismemberment of prostitutes. In spite of modern police methods, to this day no one knows who the Ripper was.
On November 7, 1872 the Mary Celeste departed New York with Captain Briggs, his wife, young daughter and a crew of eight. Expected to dock in Italy, none aboard were ever seen again. The ship itself was found floating in the middle of the Strait of Gibraltar with no signs of a struggle and everything intact except for a missing Captain’s log.
The Loch Ness is a large, deep freshwater lock in the Scottish highlands where for centuries people have been reporting sightings of a fairly large cryptid that has affectionately come to be known as “Nessie”. Not only has it been photographed repeatedly, it has even been caught on videotape – as recently as 2007. Heck, it’s even popped up on some sonar equipment. Unfortunately, however, the data and footage is never clear enough to definitively verify its existence. So, for now, it remains one of the most famous examples of cryptozoology in history.
