We KNOW that JR's clothing would've contacted JBR's hands that day. We KNOW JR's clothing would've contacted JBR's clothing. Therefore, we KNOW JR's clothing fibers would be subject to secondary trasnfer. There's just nothing that remarkable about R fibers on their own daughter. There isn't now and there sure won't ever be, not with unknown male DNA mixed with blood in the crotch of her panties! I mean, you've got to be kidding, right? That DNA matches other DNA found in two places on the waistband of her longjohns!
You've got brand new size 12 panties out of a new package that have DNA and blood on them that coincidentally occur at the same spot. You don't know what form that DNA is. That same DNA can be found in skin cell form on the longjohns! That's it right there. Are you going to buy the coincidence that the DNA and the blood got to the same spot separately and nowhere else?
Time to get real.
Besides, the fibers are just blown out of proportion by RDI. All you could ever say is that fibers 'consistent with' JR's shirt were found. You have no idea if these fibers came from JR's shirt.
For the most part HOTYH is right. And lets remember that the prosecution couldn't make the Ham Sandwich.
