Bela Kiss was a tinsmith and amateur astronomer who lived near Budapest, Hungary, at the turn of the 20th century.
When Kiss was conscripted for WWI he left his home with his housekeeper, and the yard was full of large metal drums.
He had told authorities that they were full of gasoline, so they were opened when the war created a demand for fuel.
But instead of fuel, inside they found the pickled bodies of 24 women who had punctures on their necks from a vampiric practice.
They tried to track Bela Kiss, but his name was actually very common and the war made it difficult to know where he was.
A letter alerted police that Kiss was in a Serbian hospital, but he escaped, leaving a dead soldier as a dummy in his bed.
There were many subsequent rumored sightings of Kiss, but his final whereabouts and body count are a mystery...
The MV Joyita was a merchant vessel found partly submerged near Fiji in 1955, 600 miles from her planned route.
There were no signs of her 25 passengers and crew, and the radio had been left set to the international distress signal.
Something awful must have happened, as the engine was piled with mattresses and a doctor’s bag contained bloody rags.
Even more unusual is that all the clocks had frozen at 10:25, as if some sudden shock had knocked them out.
The lifeboats were gone despite the ship’s design making her unsinkable, but no hint of the crew has ever appeared again.
On Christmas Eve, 1945, a fire broke out in the West Virginia home of George and Jennie Sodder and 9 of their children.
4 of the children were rescued, but the 5 others remained unaccounted for in the smouldering aftermath...
...and firefighters could find no bones amongst the charred debris that would have matched the missing children.
An inquest quickly ruled the fire an electrical accident despite evidence of the house being watched for several weeks...
...and witness reports of “balls of fire” being thrown at the house along with the sighting of a car full of children.
Private investigators later discovered the unburned remains of an unidentified person while excavating the site...
...and a photo of one of the children as an adult was allegedly mailed to the Sodder family in 1967.
Ray Gricar was a defence attorney who was re-elected four times in Centre County, Pennsylvania, from 1985 until 2005.
On April 15, 2005, Gricar went missing in mysterious circumstances and has since been declared legally dead without a body.
His car was found, along with his work phone, but his wallet, keys and laptop were all gone, presumably taken with him.
His laptop was later recovered from a river, but it would take several more months to find the hard drive, which was unreadable.
Gricar had earlier announced his retirement after refusing to press charges in the famous Jerry Sandusky sexual abuse case.
Some suspect Gricar’s computer contained evidence of a larger scandal and that he was silenced to protect powerful figures.
DB Cooper holds a special place in history as the only person to successfully commit piracy on a travelling aircraft.
In 1971 Cooper hijacked a Boeing 727, flying from Portland to Seattle and extorted a $1.2 million ransom in today’s money.
He told the crew he had a bomb in his briefcase, and they phoned his demands ahead to the airport in Seattle...
...where the money was collected, along with parachutes, and Cooper instructed the pilot to next fly towards Mexico.
The cabin was kept unpressurised and they were told to fly as low and slow as possible so Cooper could jump from the rear stairs.
No trace of Cooper was ever found until 1980 when several bundles of deteriorated ransom cash washed up in the Columbia River...
