I must disagree about Sylvia Browne.
On October 6, 2002, eleven year old Shawn Hornbeck disappeared while riding his bike to a friend's house in Richwood, Missouri. His anguished parents went on Montel’s TV show on February 24, 2003, to try to learn from “psychic” Sylvia Browne what might have happened to their son. Playing the odds as usual, she told them Shawn was dead ("is no longer with us"), and followed this with several guesses about where his body would be found (in a “wooded area”).
Fortunately, as you may have heard on the news this weekend, Shawn and another boy who went missing just last week, were just found alive in an apartment in Kirkwood, Missouri.
