In a Hollywood-like twist, authorities dropped charges against an Elvis impersonator accused of mailing poison to President Obama and are now investigating the man's rival, a former member of Mensa, the high-IQ organization, who was charged earlier this year with fondling underaged girls, reports the Memphis Commercial Appeal. “This past week has been a nightmare for myself and my family,” said a tearful but smiling Paul Kevin Curtis, 45. The already-strange case that started with two charges accusing Curtis of mailing ricin-laced letters to Obama, U.S. Sen. Roger Wicker (R-MS), and a Mississippi judge grew stranger yesterday when authorities released him and began searching the Tupelo, Ms., home of James Everett Dutschke, 41, a martial arts instructor, one-time political candidate, ex-Mensa member and rival to Curtis. Dutschke denies any wrongdoing. Searches of Curtis' home found no evidence of ricin, materials used in its production, or any evidence the suspect had used his computers to research the making of the deadly poison.
