Siegfried & Roy producer refuses to share mauling video Government sources say the company that produced the Siegfried and Roy magic show has refused to give federal investigators a video of the tiger attack that badly injured illusionist Roy Horn. The US Department of Agriculture tried to obtain the video through two subpoenas. But a source familiar with the case says Virginia-based Feld Entertainment would not hand over the footage. The source said the USDA would pursue other "legal avenues" but did not give specifics. Under the Animal Welfare Act, the USDA has been investigating the October attack. Horn was mauled by a 300-pound white tiger during a live performance at The Mirage hotel-casino in Las Vegas. Horn survived but later suffered a stroke that has left him partially paralyzed. The long-running show closed.
