I guess it means he must be white then. Isn't that the default race unless otherwise specified ?
There was a similar story a year or two ago (I don't know if I can find it right now) about a man who shot the manager of a KFC not too far away from where I live. The man was described as approximately 6' tall with curly hair. I teased one of my family members by saying "Hey! why'd you shoot that guy?" Anyway, no other description was given to the public, which was next to useless. It turned out the guy was a black which the media finally admitted to later.
When you see a total lack of description, most of the time, but not always, it's either a black or a nonwhite Hispanic. I think it's funny in this article they describe the vehicle but not the perpetrator.
I think it was probably an illegal immigrant but can't be sure on that one. They're the ones who usually steal things in the area that was listed in the article.
