According the official public record, Adolf Hitler committed suicide in his underground bunker as allied troops stormed Berlin at the end of World War II. But no one actually saw him die. No body was ever produced. No photographs were ever taken. Some believe Hitler managed to escape, and for years there were sightings of the former dictator in many parts of the world. Then, in the 1990s the Russians revealed secret evidence taken from Hitler's bunker decades earlier that they said proved he had died there. Among the evidence is a piece of skull. MysteryQuest obtained access to this evidence for testing, and the results are startling.

The officers of the SS, Hitler's feared paramilitary unit, were the most notorious war criminals of WWII. Some were brought to justice after the war, but many were able to escape from Germany. A massive secret organization known as Odessa was reportedly formed to help them flee and rebuild a new Reich that would again rise to power. MysteryQuest will investigate by following the path of feared Nazis from Germany, to Austria, and Italy. The team will also travel to Paraguay where many of the Nazis reportedly hid while plotting their new rise.

This island in the middle of San Francisco Bay has a forbidding reputation. Native Americans believed it to be a place of evil spirits. When it became a federal prison in 1934, only the most violent and difficult prisoners in the U.S. were sent there. It was reputed to be escape proof; only three men have ever managed to get off the island. They left in 1962 and have never been found. MysteryQuest investigates to determine whether they could have survived the icy waters of San Francisco Bay.

In one of the earliest documented serial murder cases, sex workers in the Whitechapel district of London were found brutally murdered with throats slashed and bodies mutilated. All the deaths were attributed to one man: Jack the Ripper. Never solved, the accepted theory is that the killer was a local madman. Now, 120 years later new evidence indicates two surprising new theories: the killer might have been a woman, or the killer was not English, but American. MysteryQuest's team of experts heads to London to follow these leads and examine the evidence firsthand.

A series of unsolved murders. A cryptic set of clues. A dead end at every corner. The serial killer known as the Zodiac long terrorized the residents of the San Francisco Bay area while taunting police. He was never caught. Now our team of investigators have identified a new suspect, and with the aid of a groundbreaking new DNA technology have the chance to come one step closer to finally solving the mystery of this murderous crime spree.

The Amityville Horror was perhaps history's most famous haunting. Nearly every known form of paranormal activity was experienced in this Long Island home. Could the spirit have returned? There are eerily similar phenomena occurring in a new location. MysteryQuest investigates using new technology built specifically for their investigation as they try to prove that these demonic spirits not only exist but have taken over.

To this day no one knows the true purpose of Stonehenge, the ancient monument in the British countryside. There are many theories: a shrine celebrating a god; an ancient solar calendar; or maybe a sacrificial altar for an unknown pagan religion. MysteryQuest travels to the ancient ruin with a new theory--that ancient people may have used the sound reverberations inside this circle to induce a trance-like state among participants in ancient rituals. Were there bizarre rituals, even sacrifices, to some long-forgotten god? The team will attempt to find evidence that could crack open this persistent mystery.

This special explores the evidence, questions, conspiracies, and eyewitness accounts surrounding the theories of time travel that have captivated the world.
