____________________Mark Waterbury is talking specifically about testing things from the 'pile of debris' in which the bra clasp was found when it was finally collected. The sock wasn't found in that pile of debris, was it? If it was, did they test anything else from that pile? They should have tested objects (plural) found with the sock not for investigative reasons, but as a control test. Unfortunately, like negative controls on the knife, they didn't do it (AKAIK, anyway). You might as well say they don't need to carry out control tests at all as long as they test more than one object from the scene.
Also, doesn't Massei say the reason Meredith's DNA wasn't found on the sock was because they only tested a couple of places on it, while her DNA was probably on other parts of it?
Let me correct myself. Merdith's DNA was found on her sock where spots of her blood were found. Her DNA was not found on the elastic band, where one might expect to find DNA due to skin contact.
And I find only among the Innocentisti a reference to the clasp being found in a "pile of debris."
And why wouldn't any tested article exposed to the dust on Merdith's bedroom floor constitute a "control"?
