The people were supposedly there when LEO conducted their door knocks in the next few days.
The man did a short interview in the paper....saying he met the VD's and Danielle on FRIDAY when she sold him cookies.
An empty house next door sure seems like an inviting place for a kid to want to explore, especially when mom and dad are both gone for a while. (which they were on Friday afternoon.)
It also seems a likely place for someone to take a child they just kidnapped to, before transporting them.
So many possibilities.
