Your problem, Roy, is you can't seem to understand that no one is going to ever be convicted on that DNA. Not the Ramseys; not a stranger/intruder.
There is a mountain of evidence in this case that has never been and will never be traced to anyone, anywhere, but the Ramseys and their home.
Period.
Considering that Patsy wrote the ransom note, that JonBenet was being molested before the night she was murdered, and that the Ramseys have covered up for the molester and killer for 15 years, it's a no-brainer: the Ramseys did it. All of it.
Following the evidence, John and Patsy handled the body: Patsy's clothing fibers were tied into the knots of the garrote; John's shirt fibers were found in the genital area where the victim had been wiped down before she was redressed. The staging was so obvious, even John realized the weaknesses when he was allowed to "find" the body and told Arndt it was an inside job.
I don't know you or what kind of stake you have in this case. What I do know is no one who can objectively look at the actual, factual evidence in this case can possibly rule the Ramseys out.
What Beckner was acknowledging--what everyone in LE has to accept at this point--is this: Team Ramsey has had two corrupt D.A's., both of whom hired and worked with Ramsey master-propagandist Lou Smit and his cronies; they also had a powerful Defense Team even O.J. would envy; by the time Hunter buried the grand jury, the Ramseys had hired media and civil law expert Lin Wood casting a long shadow over anyone who dares to speak the truth about this case; throw in self-promoting, international propagandist Michael Tracey providing 15 years of public relations spin and faux suspects, and it would take someone with either incredible heart or incredible balls to stand against this juggernaut of injustice. There is equally little doubt much went on behind the legal and media scenes which was influenced by the heady power of Lockheed Martin's undeniable world-class connections, burying evidence, creating disinformation at every twist and turn. Even Beckner knew when he was defeated. He probably knew it on Day Two, in fact.
So of course, the DNA at this point would have to be sourced to try anyone--ANYONE. How many ignorant people now say, Oh, the Ramseys have bee PROVEN innocent with that DNA, haven't they?
But if they found that DNA donor tomorrow, and even if he were a child molester who for decades lived in Boulder, that would NOT be enough to convict him. Not in any court, anywhere.
All any defense attorney will ever have to bring up in front of a jury/judge is the ransom note and that Patsy could NOT be eliminated as its author/writer, the many evasions and lies the Ramseys told LE, their "inconclusive" results from TWO of THEIR OWN self-sponsored polygraph examiners, and the fact that LE/Hunter/Lacy NEVER got copies of the Ramseys full cell phone records with any subpoena, nor for their clothes, for that matter. The fibers, the autopsy evidence--what DA is going to explain how that "stranger intruder" managed to molest carefully watched JonBenet right under her family's noses, and they never caught on? Or more incredulous, they helped cover it up then, too, even after she was murdered? There are not 12 people outside a nut farm who would believe there's no reasonable doubt some stranger committed this crime because A FEW SKIN CELLS from him were harvested during mucho evidence processing by MANY labs and technicians over a period of 12 years--surely lab contamination is impossible!
Didn't you ever wonder why Team Ramsey was always so willing to concede this "intruder" could be dead? Ha! He could have been already dead when JonBenet was murdered, lying in a morgue somewhere while his autopsy or case evidence was being processed--a few skin cells handled by a lab tech who had no idea how easily this case would be thwarted with future, overly sensitive DNA-testing that would prove--nothing!
So you hang on to that DNA for dear life: SKIN CELLS, my man. Not blood; not semen; SKIN CELLS, of which we all shed thousands a day--look at those dust bunnies under your bed and couch.
Hang on to it, because it's all you're ever going to have.
And Burke is going to live his entire life under that umbrella of suspicion, because his parents were so arrogant, so egotistical, so without responsibility and parental duty to their molested, beaten, and strangled child, that instead of doing the right thing and calling for professional help, handling the sickness that was theirs to answer for under the laws any of the rest of us would have been subjected to, they chose to burden society and innumerable innocent people with their lies and crimes.
Imagine if they'd only swallowed their pride and gotten help when it was discovered she was first being molested.
Oh well. That's the nature of incest; take it to the grave. So one or more of them helped her do that, with some intent at least, IMO.
