Maybe. But I think Corey and de la Rionda are fully capable of making things up, without Crump's help. In this case, the state was able to research the passport status, where Crump would not have been able to, and likewise the state has access to the recorded phone conversations. I wonder why it took the state over a month to act on what it knew.
Clearly they didn't fear that he was a flight risk or they would have or should have acted sooner. I'll bet the depositions that have been ongoing since May 14th have not been going well for the prosecution, and this was their temper tantrum.
