John wore the shirt on Christmas day - he played on the floor withthe kids, he carried her to her bed - her hands may have touched his shirt and she may have transferred the fibbers to any part of her body - - -

I really wouldn't have a problm with that BUT

I don't believe the fibers matched and I am not going to toss what could be great evidence in this case. Could be from the sleeve of an intruder - someone who had no reason to be in that house or near that child.
