Could there have been any sort of collusion between either of the two boys with one or more of the witnesses?

Listen to the Serial Episode and post a thoughtful question in our class forum as described in the Syllabus.  Some of the subjects in this episode related to the legal aspects of evidence and procedure include the following:
Credibility of witnesses
Corroboration
Police Interrogation of suspects
What would a sociopath’s response sound like?
“Admit nothing, deny everything, demand proof” defense
Respond thoughtfully to at least one other student’s question as described in the Syllabus.
The contrasting stories of Laura and the neighbor boy seem to further the divide between the two possible versions of events: what Jay says happened and what Adnan says happened. The question that raises for me is this: could there have been any sort of collusion between either of the two boys with one or more of the witnesses?
