Let them eat cake:
There was a funnel web that connected the iron grating over the window well to the window frame which was not disturbed and which was broken when opened by LE after photos. Entomologists identified the spider and noted that such a spider could not make that web in a few hours but most importantly did not make webs in the winter. So, the undisturbed web was crucial to eliminate the 'intruder through the basement window' theory. Another web was formed in the lower left corner of the window opening which would have been eradicated by anyone sliding through that narrow space. It too remained intact.
Debris from the window well was undisturbed meaning no one stood on it or slid over it to get through the window. No debris was found on the floor under the window which necessarily would have clung to the shoes and clothing of the 'intruder' and fallen off as he landed into the basement or have been brushed into the house as he slid through the tiny opening.
No one entered through that window that night. Period.
The DA 'cleared' the Rs on tDna which, if taken as a whole and on it's face, would mean that SIX people were in the house, molesting and killing JBR. SIX. Yep, SIX different human tDNA cells were found on JBR's body, at least one was a female. The DA never suggested that a team of intruders committed this murder but following the logic that tDNA proved the R innocence should have noted the SIX foreign samples found. Further, the tDNA from the underpants and longjohns on which the DA based her claims is in fact mixed DNA from 2 individuals, not one, and consists of only 4 markers, not the requisite 13 to make a profile. It was junk, evidence of nothing.
Then consider that all brand new clothing has human cells on it and that brand new panties in the package would be contaminated with human cells from workers in the manufacturing process, and the idea that the tDNA found eliminated the parents is simply preposterous.
