Hi Jessiealan, I believe DNA evidence on Jon's underwear exonerated all members of the family.They apparently thimk that the killer entered the home whilst the family were out.
Yes, Lassie, but there are some in the U.S. who do not want to let go of the idea the family was responsible. They have tried to persecute the family for years and now, a show on CBS TV has released an opinion (in spite of evidence it is not true) that the brother is guilty. It looks as if the Ramseys might take them to court. I hope so.
