This was HIS house, HIS bathroom, HIS trash can, and a bathroom one at that. Full of all kinds of yicky DNA. And that can rub off on anything it comes into contact with. A bit of DNA found on a discarded plastic nail means absolutely nothing.Excellent post. I noted that the lawyer took pains to debunk the DNA-under-the-fingernail scenario. There was DNA on it, the nail is sticky on one side (no personal knowledge here), and indeed lots of DNA in the wastebasket.

I can't believe the nail was even examined for any DNA which matched these boys. There certainly are rules regarding contamination and CHAIN OF CUSTODY. One big rule: Change your gloves and change them often.
