The Missing Evidence Full Episode Guide

  • Is believing in the Loch Ness Monster's existence really so outlandish? Kangaroos, giant squids, and even tigers were once considered mythical creatures. And a fish thought to be extinct for 65 million years was caught off the South African coast in 1938. It's possible something foreign to us could be hiding in the Scottish lake's cold depths, but is it probable? A detailed study exposes the truth behind the phenomenon, and investigates 80 years of photographs, videos, and thousands of eyewitness accounts.

  • 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.

  • Something strange is happening in the Sierra Nevada skies. Over several decades, an estimated 2,000 aviation incidents have occurred there, with death tolls and disappearances far outnumbering those of the Bermuda Triangle. Why have so many pilots lost their lives or simply vanished without a trace? 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.

  • 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.
