The Vidocq Society, the international pro-bono crime-fighting organization that Walter helped establish, investigated the allegations and also cleared him of wrongdoing. In the course of writing his book on the Vidocq Society, "The Murder Room", New York Times-bestselling author Michael Capuzzo investigated the allegations and found them groundless. Capuzzo interviewed Vidocq Society President William Fleisher, a federal agent with the FBI and U.S. Customs for more than 20 years."Richard got a bum deal," Fleisher said. "A convicted killer made defamatory stuff up about him and got a court to believe it because nobody bothered to check whether the killer was telling the truth, which is ridiculous. Richard became a victim without a remedy. Courts make mistakes, and this one did."
