I spoke with him again. She never returned his attempts to contact her, and he has asked a LE agency where she supposedly lives to go out and try to contact her in person.
But nothing has been done, and all my contact can tell me is that these things take time. He says that he hasn't dropped the case, but with the other agency taking their time, he is at a stand-still as to what he can do.
He still won't give me any of the info that he has on her (e.g., DOB, current hometown, married name, etc.)
I'm concerned that the Alcala New York trial will come and go, and any information that WF has that might be helpful to their case will have gone unexplored.
