A Utah woman has been arrested on suspicion of possessing a biological agent of mass destruction, though police say she had only enough of it to affect one person. Authorities say 50-year-old  Janie Lynn Ridd bought the unspecified biological agent online and gave misleading statements before her arrest on Wednesday. The Utah Department of Public Safety officials refused to say what she bought, But the agency says there  was never a threat to the public that Ridd had no plans to target large groups of people. Sgt. Nick Street tells the Salt Lake Tribune she purchased enough to affect one person.
