I had a thought …

I was reading around this weekend and read a comment on a blog some place that has me thinking.
Why haven’t any of the Anthony’s used the foundation to help support a search for Zanny? Since Casey is using the nanny as her defense wouldn’t it only make sense to pour every resource into finding her?
Cindy did claim Caylee was still alive some where, right? So they have this foundation sitting there doing nothing?
Why?
