The mysterious circumstances surrounding Marilyn Monroe's death are more shocking and explosive than any Hollywood crime drama, involving celebrities, spies, the mafia, the FBI, and one of America's most powerful political families. While there's no hard proof she was murdered, missing evidence and disclosures by the FBI and Monroe's associates suggest the full story of her last day is far different than what the official record suggests. A storm of innuendo and eyewitness accounts are used to investigate the sensational death of a superstar.

The World Trade Center towers were once the tallest buildings in the world, marvels of engineering and architecture. But on 9/11, within two hours of being hit by a terrorist attack, they collapsed. The official report has left many questions unanswered and spawned countless conspiracy theories. But two scientists, working independently, have come up with the same new theory, based on missing evidence, which may finally explain what happened on that tragic morning.

The identity of Jack the Ripper is the greatest mystery in the history of British crime. For three decades, Swedish journalist Christer Holmgren has sifted through over 120 years of clues, searching for evidence that will unravel the case and reveal the true killer.

Holmgren and a team of historians, detectives, and forensic pathologists revisit crime scenes and examine a series of eerie coincidences that tie six extraordinary murders to one ordinary man.

A detailed study exposes the truth behind the phenomenon, and investigates 80 years of photographs, videos, and thousands of eyewitness accounts.

The phenomenon is explored on the ground and in the air, in hot deserts, cold mountains, high-tech labs, and even the outskirts of Area 51, all in search of the deadly truth of the Nevada Triangle.

Is a strange primate, standing 10 feet tall and weighing in at a thousand pounds, roaming the dense forests of the Pacific Northwest?

So who, or what, is this mythic creature? Scientists examine the facts, use rigorous analysis, and pull together missing evidence to find the truth behind the hairy legend.
