Without proof of the crime, it would be considered a rumor, possibly slander by RD's attorney, IMO. If he had direct knowledge, LE would have to have the proof in order to verify if he was being truthful with his information. IMO, it's no different than any other witness. Just because you think that someone is "capable" of committing a crime does not mean they are "culpable."
IMO, a combination of all his odd behavior, violent outbursts, etc....made almost everyone familiar with the crime think that RD did it. Proving it has been the problem the whole time, IMO, combined with lack of people trying to prove it....
ALL JMO
The all elusive PROOF! No head, no body, no prints.........It makes me crazy. So many places, names, players. If I had a theory as to Doug's involvement it would include Morris and Meyer Black, The Durst Pine Plains Farm and Carvel property. Just IMO
