how would you put together all we have seen? he learned a lot three hours, one of the hostages has been released. we have learned more about this desire to have sadiq kwu i released. where does this stand? reporter: i think in the past couple hours, things are changing. they have provided information on mr. there is a weapon. i assume there is. on the mental state of that individual, it s been a long time. this is an official length of time for a hostage investigation. so one of the questions is the emotional state of the person of the tahj u hostage-taker is declining over time. the fbi team on the phone is getting the same idea. is this person slipping away? i d say finally, you got to presume the bureau identified this individual.
