I don't think investigators found the original roll of tape or cord. Nor did they find any other application in the house where either material was used.
In the photos, all cord ends appear freshly cut, and the cord itself appears new (not dirty or worn, as if taken from elsewhere in the house where it was originally used for another purpose).
This gives the appearance that both the cord and tape were brought in for the purpose of kidnapping or killing JBR, not improvised from materials already on hand, originally intended for another purpose.
The DNA could not have originated anywhere, as you claim. It could only originate with one person. The question is, was this person's old, degraded DNA deposited there innocently or not. You don't know which until you match the DNA. The fact that the DNA was old and degraded has nothing to do with when it was transferred to JBR's underwear. There's no requirement that only fresh, complete DNA can be deposited on JBR's underwear.
Holdontoyourhat,
In the photos, all cord ends appear freshly cut, and the cord itself appears new (not dirty or worn, as if taken from elsewhere in the house where it was originally used for another purpose).
This does not mean any roll of nylon cord was new, or arrived on a roll, it may have been wrapped in cellophane?
This gives the appearance that both the cord and tape were brought in for the purpose of kidnapping or killing JBR, not improvised from materials already on hand, originally intended for another purpose.
Sure it gives the appearance, but appearances can be deceptive, particularly when you know you are dealing with a staged crime-scene, so why did the intruder deliberately wipe the flashlight clean, inside and out, then leave it at the crime-scene, but remove any remaining tape or cord?
The DNA could not have originated anywhere, as you claim.
Of course it could, it may have originated from a toilet seat at the Whites, or from any floor JonBenet sat on, or from any location through which the underwear passed from the manufacture of the material on a roll to its patterned cutting at the underwear factory, then as the underwear was sewn together any person may have sneezed depositing the now
degraded dna.
JonBenet will most likely have other examples of degraded dna on her body e.g. her hands , under her nails, her feet, but these will be recognized for being what they are, e.g. random degraded dna.
Also the degraded dna is to be found on her clean out of the packet size-12 underwear, why not on her white gap-top, or her longjohns, or on her genitals. Most likely because the dna was already present on the size-12's?
