So, September 5 is the next big day ... Monday. Maresca, who has recently been heavily criticised, will have a chance to cross examine the witnesses ... should be interesting. Then we have to wait for the decision.
Personally, I think the question of contamination is weak, particularly because there were 6 and 12 day intervals between the testing of the knife or bra clasp and the last related use of the machines. Contamination in the field is ruled out for the knife and the DNA on the blade is a match to Meredith ... if it wasn't contaminated in the field and it wasn't contaminated in the lab, then it wasn't contaminated and the DNA match on the blade means the knife was in contact with Meredith during the murder.
