The rumors that he yelled the name of a female during the shooting were posts from twitter. I have followed all the Seattle news stations including facebook posts claiming they talked to people who were in the store or close enough to hear the shots and none of them have said that.
I would suspect from the photographs that they know who this is or have an idea who it is. The pictures are more than adequate for someone to recognize him. The make-up counter seems to be an odd target (more people in other spots of the mall generally) and the employees there are often young and pretty so I think we need to wait and let this develop before we draw big conclusions beyond the fact that this was a cowardly attack that tragically took the lives of 5 people.
You’re right, there’s too much we don’t know yet. I was just struck by there not being any witness interviews in the media.
