Suppose this is what happened:
AB goes to the airport early to meet the biological mother of Zahra, while waiting, his conscience spoke to him and decided upon himself, enough of this, then he called the police to give a statement of new information. The cops go and pick him up, another officer remains at the airport to meet the family member and escorts her to a local hotel or place to bed down at. While at the station they read him his rights, and AB gives them more. They head out to several search area's and find some leads, no body but enough leads to bring EB to one of the search sites to show her that AB is talking and to show her the JIG is up. Hoping that EB will confess and lead them to Zahra. Attorney gets word, leaves and is now on scene and advises EB to not talk. Now the case is stuck, so the cops have to regroup and go over what they found with AB again.
