Presser - they do not think parents are involved. Continue to work in area of disappearance, don't want to miss anything.

In answer to question whether parents took polygraphs, not going to answer that question but "confident" parents are not involved.
Tips across country - Texas, Nevada, Maryland, Maine. Don't focus on particular story.
Eliminated parents, but unable to answer if other family members have been cleared.
