My son is at his fraternity house now and is going to try and talk to the guy that saw the blast and get the info on the girlfriend from Iran. He hasn't lived in the house in two years and is a Grad Student and GA so he didn't know the girlfriend but when my daughter and I described her, he knew her boyfriend.
try and find out how far both the "suicide" detonation and the police induced detonation were from the location of the buses. what time of day did this occur? was it still light out? does the area near the buses have security, is it well lit, is it in a visible area where people would take notice of someone attaching a bomb to the side or underneath a bus?
