Google the phrase "Sylvia Browne fraud." You'll be reading for a while. Does your niece know she was convicted of grand theft and investment fraud in 1992?
The crap that really infuriates me is when Browne sticks her nose into a missing-persons case. People in that situation are already hurting enough, and the last thing they need is Browne making bad guesses about the fate of their loved ones:
In 2002, Browne told Lynda McClelland's daughters that their mother had been abducted by a man with the initials "MJ" and taken to Orlando, Florida, but was still alive. McClelland's body was found buried less than two miles from her home in Pennsylvania. The man charged and convicted for the murder was David Repasky, McClelland's son-in-law, who was present for the reading.
In 2003, Browne claimed that eleven year old Shawn Hornbeck had been abducted by a very tall man with long black dreadlocks and a blue sedan, and that his body could be found near two large, jagged boulders in a wooded area about 20 miles southwest of Richwoods. Her claims led to a refocusing of search efforts of numerous people calling in with tips regarding possible spottings of the rock formations Browne had mentioned. Hornbeck was found alive four years later, having been abducted by a white man with short brown hair who drove a small white Nissan pickup.http://en.wikipedia.org/wiki/Sylvia_BrowneHere's an interesting site from Isabella Snow, a woo who claims psychic powers herself:
