Its all good.
I wanted to know what you meant by ,":you cant make sense of what this means . ''
I just want to point out that if a condemn was found in the park with a 9 year olds DNA on it, we would have a clear direction to look for a suspect.
In no normal world is that an acceptable fact , so .. the case would move forward.
(To be clear, I never pictured the victim in this hypo as a child lol.)
But getting back to Asha's case: we know, for instance, that many items were collected around the area where the trash bags containing Asha's book bag was found (it's disclosed in the search warrant). You don't know how long ago those trash bags were discarded. There's a Coke can nearby, a cigarette butt etc. It's hard to make sense of all of this.
At some point, the saliva DNA found in the Coke can discarded in the site the trash bag was found points to a pedophile whose DNA was put into CODIS. That can be something, or just an unrelated predator etc.
The trash bag itself had been manipulated by the people who found it, and that's transfer DNA already. You can rule out some of the workers. It was a construction site, so if one of the workers was an unregistered immigrant that didn't come forward to speak with the police, that's already a sample you can't make sense of or rule out as an innocent transfer or not...
Some items in Asha's bookbag weren't identified by her parents as belonging to her, so the hair of a 13 y.o. found in an undershirt could have been transferred from a different item. It's all open to interpretation and investigators could have many alternative theories.
People are excited about the Dedmons being named as suspects in a high-profile case that had no fresh leads for decades, I get it. But, objectively, my view of the current state of the investigation is that the girl's hair and the green car 'sighting' is all investigators have to go on. They MUST pursue this. That doesn't mean they BELIEVE these people were involved, it's just the best they could get so far.
