DNA in a plastic zip lock bag

I wish that I had thought to keep more unwashed clothes of Austin's, but I was totally unprepared to deal with the loss of him. I just did what I thought I was "supposed" to do. Which was clean up, give to charity, box up and store away and even throw away his belongings. No one told me "what to do" except I knew that I had to empty his apt. quickly and I was afraid that I would be responsible for the remainder of his lease because I co-signed for him. I kept his folded laundry on top of my dryer for a long time (until I replaced the old dryer) because it looked like he may came home and, grab his clothes, and say, "Thanks, Mom, you didn't have to do that!", like he always did. I did take his washcloth and bar of soap from his shower...thinking that I would always have his DNA in a plastic zip lock bag.I miss that big teddy bear of a sweet kid so bad...
