What was the harness's other end attached to?

There are multiple episodes specifically about matching mitochondrial DNA with the suspect's mother, which was my specific question. :)

So matching mitochondrial DNA doesn't actually mean much in the context of forensics then, because you could also match with your 13th cousin 6 times removed and for all you know there are 17 of them in your village?

(I am zero surprised a TV show is wrong about science, by the way.)

Ah so it does mutate. So when Forensic Files says they got an "exact match" it's not necessarily true that one will perfectly match one's mother?

Okay so this reminded me of a question I had from watching too much Forensic Files:

If mitochondrial DNA is passed down identically from mother to child how is it that we don't all (all humans) have the same mitochondrial DNA from this Mitochondrial Eve?

This is 100000% a plushie, and the cutest plushie ever.
