While what Ray A. has to say is of interest, he says that he is getting his information from JR's roommates who were back East at their parents' homes, and those roommates in the NE were getting the information from someone close to the POIs and Lauren in Indiana; it is not solid information. It is too removed to be reliable as to specifics re: who dialed, who was called, or anything else, really. I have trouble thinking of Ray A. as being "very close to the events..." as sweet_blush states.
