FINALLY. I find the day when they had 'scent' clothing for the dogs to trail. :
11/26/12
Absent any clues, we owe it to Dylan to consider all possibilities, Bender said. We will continue to do so.
None of Dylans belongings that could carry his scent was available in the first days of the investigation. But the family had articles of the boys clothing delivered on the weekend.
We have the clothes, Bender said Monday. We dont need them here (at the reservoir), but can use them later.
Elaine Redwine doesnt believe her son is a runaway because it wasnt his nature and because he was happy at his new school in Colorado Springs where he entered eighth grade this fall.
Its no comfort that they didnt find anything in the water today, she said Monday. But just looking for your little boy in a lake is horrific.
Bender said no search is planned for today, but searches will resume if new clues or leads develop.

So that sounds like it was quite some time before they ever got any of Dylans clothing with his scent. So I still believe they NEVER tried to track his trail leaving from Dad's front door.

:what:
