unwitting? >> no, not as of right now. you know, one of the things as an investigator, what i would want to do if i was assigned to this case, wolf, would be to go to these different hotels. we know he stayed at numerous hotels. try to get the video surveillance. they would probably keep it for about a month. who was he with? was he inside the hotel, outside the hotel? did he meet with anyone? i think that's why the fbi was asking for the assistance of the public. if you saw this guy, call us. from there, they can ask questions. did you ever see him with anyone? where would he frequent? all these are part of the investigation on finding out what made this guy tick, wolf. >> mike brooks, thanks very much. lots to investigate right now. multiple agencies doing it. today we also know the names of all of the victims killed in the shooting. we're going to tell you about their lives. also, we're learning some truly remarkable stories of survival. this is cnn's special live coverage. we'll continue right after this.
