Maybe the surviving family, friends and community leaders should call their own Town Hall Meeting on the case. Invite all the elected officials - especially all the ones who have kept silent on this murder. The ones who have done nothing, haven't visited the town or the families. State Rep, State Senator, Congressperson, US Senators, Governor. Call the news media and have them attend. Public pressure is the only way to get a response. If any elected official refuses the invite, call the news media and let it be known.
I'd be happy to help coordinate.
I wonder if the average local citizen really cares if it gets solved or if they assume the Rhodens got what they had coming and it doesn't matter who did it....
