Maybe you haven't seen this:
"Ressler [in response to a question]: Yeah, I've been to Boulder on two occasions. I've talked to a number of people in the law enforcement field, the medical field, the prosecutor, one of the prosecutors out there, even some of the domestic help of uh, the Ramseys and uh, some media people as well. I do not-- uh, I've been to the location of the house, I've been around the house, I've looked at the neighborhood and I do not ascribe at all to the concept that a stranger broke into the house and, uh, in an attempt to kidnap or abduct JonBenet, killed her and wrote the note, and then left. I believe it was some sort of an internal--- uh-- situation that occurred that-- uh--I believe the Ramseys-- Mr. and Mrs. Ramsey, possibly their son-- uh-- Burke, have more information available that they could provide police than they've held back-- uh-- in their non-cooperation they've put themselves in a position of being major suspects. It's very likely they're going to be indited in the Grand Jury here in April-- uh-- and whether or not there's enough to prosecute-- uh-- them to the point of conviction remains to be seen. But I think-- uh-- I've always believed that JonBenet was killed as a result of an accident that was being covered up-- I'm not saying whether or not Ramsey's parents or the brother were involved in the actual killing, but I think--as I say--I think that the entire-- uh-- elaborate staging was done to conceal the true facts of what really happened to that child."
