Without a source: From another forum, one very knowledgible (we really need spell check) individual states they have evidence, but not motive or how it was done. So far the evidence is the DNA in the RV and the finger prints. No DNA evidence of him in the VD house or Dani's room. Plus over 100 unidentified finger prints from the RV. What happened to that anal-retentive-ocd-clean freak? That my friends leaves you with Well, we have someone but DID he do it.
My vote for David is NO. Give me more credible evidence and we'll talk. Thanks, have a nice day.
