When I read that the suspect was Hispanic, I assumed witnesses told investigators something they overheard that led them to that conclusion. A spokesperson from the Washington state police just said on Fox that they weren't aware of any statements made by the shooter. Maybe his choice of victims led to their conclusions, a link to one or more of the victims that hasn't been made public. Maybe eyewitnesses said they believed the suspect was Hispanic. Just going by the released pic, I think the suspect looks like he could be of Greek ancestry, Middle Eastern, or a "Goth kid" with dyed black hair and eye makeup or any of several ethnic backgrounds, including Hispanic. Surely there is much more CCTV video from the mall. All MOO. My first thought was that the shooter had some sort of relationship to at least one of the victims, family or romantic. Now I am more inclined to think random as time passes.
