I read Culhane's (blonde analyst) testimony again last night, the amount of DNA on that key was very minimal. She swabbed the whole key, black part and key, and got a very low amount of DNA on the swab. I don't think his DNA had to be planted, I think it was there in the trailer, whether on the gloves of whoever picked it up (or put it down LOL) or even from the floor/slippers. I did not read that the clasp was even tested. The same was for the latch, it was a very minute amount. The latch could not be ruled out as blood, because she had such a low amount, no presumptive tests were done.
Another thing I read that I didn't think much of before. SA's buccal swabs from 2003, when sent back to Manitowoc County Sheriff's, it was Detective Remiker that signed for them.
