The Fox News reporter who made that statement, Carol McKinley, has a history of covering the Ramseys, i.e. she got them to agree to an interview after they moved to Atlanta and said she was going to ask them tough questions. It turned out to be a "Love in." I don't know why, but IMO McKinley wimped out.
Also, I believe there is plenty of evidence to indicate that an intruder murdered JBR, so in that case, the statement she made is incorrect. The Ramseys and their attorney (who never loses a case, the defendants always wisely settle) believe it to have been slander.
All in IMO, of course.
