Ok, I just read the report. One hair was found, by Dr. Lee in the trunk - could have been missed, could have been from anyone poking their head into the trunk without being suited up. 3 hairs were found by Dr. Lee on various items referred to as garbage or trash - same scenario. All the other hairs were found after Dr. Lee left. Now, conduct a small experiment - open a newspaper and put it on the counter, check it over for hairs, remove any that you find. Next - and here it gets tricky Hot Dog, cause I have no idea if you are male or female, so bear with me - lean over the newspaper, shake your head from side to side, or brush your fingers through your hair. Rub your bare arms a couple of times. Now check the newspaper again - see any hair? If anyone suited up - especially those cute little caps, hair might have been caught as they put the cap on and then dislodged as they moved around. Hair might have been dislodged when their arms rubbed against their sleeves and dropped out.
My own assignment is to wade through the last doc dump to see if the results of testing all these particular hair samples were in there. I think your assignment is going to be eaiser than mine!
