I just came back from a visit to Target. While there, I was to buy some throws for the furniture. One of the items I bought was this: http://s92053900.onlinehome.us/cordonthrow1.jpg So, whereas I had not been before, today I am now educated in the fact that cord is used as a decorative packaging element for throws. This particular brand was a Woolrich Jacquard Berber throw, and I can find other examples online of this packaging technique. The cord on my purchase is not nylon as the ligature was, but the simple fact of cord being used in connection with throws does open the door for an explanation of how a length of cord could be in a house, yet not yield up the rest of the roll. I now have a length of cord. If it were to be used to strangle someone, nobody searching through my house would find the rest of it, ever. Does that mean an intruder brought it in? Of course not.
