Then by that same "logic", the touch DNA found doesn't mean ANY of the owners are JonBenet's killers.
And there cannot be two sources for the same DNA. DNA is unique to the individual/source. The source of any DNA is the person to whom it belongs.
So I don't know whay you keep saying "two sources of the same DNA" since that is just not possible. :waitasec:
If, however, you are trying to say that TDNA from the same source was found in two different places on JBR's clothing, then it still isn't significant. She could have picked up someones TDNA on her hand and then in the bathroom transferred it to both her panties and the waistband of her longjohns when pulling them up.
This isn't DNA from blood or semen or even saliva. We are talking skin flakes or dried sweat droplets. They can land anywhere and unlike blood or semen which should never be on a little girl's panties

, they are not necessarily nefarious leavings, but amazingly common.
There is no smoking gun in the TDNA, but if there is, as you seem bent on proselytizing, then the TDNA from all SIX sources should be viewed as left by her killers.
And that's just bologna.
