Location, location, location, it’s all about locations and we’re talking about DNA found in INCRIMNATING locations.<quoted text>
Good point, also don't forget the possibility of transfer. She hadn't had a bath since Christmas Eve afternoon and she was on her floors Christmas morning and the White's floors playing Christmas night, and she played with neighborhood kids during Christmas day. How many opportunities were there in just those three instances to get foreign DNA on herself without any connection to her murder?
If DNA transfer happens as easily as SOME seem to believe than jbr should have been transferring mom and dad’s and bro’s DNA all over the place. Yeah, you might find some stranger’s DNA in there somewhere, but most of that transfer is going to be from family and from MOST RECENT CONTACT (most recent contact includes KILLER).
Also, secondary, etc transfer most often results in mixed profiles – you transfer your DNA along with the DNA from some other.
Secondary, etc transfer does occur, but is not likely in this case because of the three specific incriminating locations in conjunction with the failure, despite effort, to link this to any innocent source.
