A. WELL, I THINK THE FIBER CERTAINLY COULD HAVE BEEN THERE FOR AS LONG AS THE BODY WAS IN ITS RESTING LOCATION. THINK IT'S UNLIKELY THE FIBER WAS THERE FOR MUCH PRIOR TO THAT BECAUSE IT WAS TANGLED IN SUCH A LARGE WAD OF HAIR ON THE NECKLACE.
Now, read that carefully. The fiber "was tangled in such a large wad of hair on the necklace."
It is very clear.
