chad wagner, decided to let us reopen the case. and when we reopened the case, because of chief wagner, it was found that there were multiple mistakes made. and in that part of portugal, there were many retired pedophiles, convicted child pornographers, english pedophiles that lived around that hotel. and the police didn't interview half of those guys initially. >> you made it clear where you stand with her parents, and that you went and met with him and were convinced of their not having a role in it. they were suspects at one point and obviously were cleared. is it right for investigators to look at them again? >> first of all, i think the portuguese police did a horrible job. normally you interview the parents, like reve and i were separated, polygraphed and police eliminate them. that wasn't done. for the portuguese police to take the scrutiny of the world hot spotlight off of them was to point the finger at the mccanns. that brutalized that family.
