Siegfried & Roy, Part 1 - The Tiger Attack (9-10p)

For decades, Siegfried and Roy dazzled millions of visitors to Las Vegas with their spectacular and unique brand of magic, co-starring with some of the world’s most dangerous wild animals. These master illusionists who could seemingly make elephants, lions and tigers disappear into thin air, were the undisputed kings of the Las Vegas Strip.  Their show brought in millions of dollars a year and the eccentric duo were beloved celebrities, show-casing the white tigers they raised from cubs and who lived on their property.  But on October 3, 2003, their wildly successful run came to an abrupt and shocking end.  In the middle of a show, one of their prized white tigers, a 380-pound male named Mantacore, bit Roy Horn in the neck and dragged him offstage in front of a horrified live audience.  The world held its breath as Roy Horn fought for his life.   He made it back from the brink of death, but the marquee show was shuttered, never to open again.  Since then, Siegfried and Roy have stuck to their version of what occurred that night, telling the world that the tiger was not attacking Roy,  rather he was trying to save his best human friend from a medical emergency by grabbing him by the neck and pulling him backstage to safety.

Siegfried & Roy, Part 2 - Dangerous Illusion (9-10p)

One of Siegfried and Roy’s former employees, a tiger trainer called Chris Lawrence, went public disputing their version of events on the night of October 3rd, 2003 when Mantacore, an adult white tiger, bit Roy Horn’s neck and dragged him backstage.  Investigating his claims led How it Really Happened to interview two others who had been attacked by the duo’s big cats, a former child acrobat named Sean Stanek and an employee named Charles Flannery.  These attacks received very little public attention, were the stories purposely buried?  Eye-witnesses, award-winning reporters and big cat experts also questioned whether the story about Mantacore saving Roy’s life was just another illusion presented by the magicians.  Did Roy do something out of the usual on stage that fateful night?  Was the truth covered up with the help of powerful allies?  Did the wealth and fame of Siegfried and Roy’s act allow them to present an alternative version of events?  How It Really Happened  investigates long-buried secrets and Siegfried and Roy’s limitations over the mastery of wild animals.
