Oh, never mind, as it does not say they were White, I will now allow my cognitive powers to kick in.
I hate to say it, but if a violent crime occurs in California, Texas, or Arizona, people assume the perp is usually the member of a certain racial/ethnic group. If a crime occurs in the urban upper midwest or southeast, to say nothing of the urban eastern seaboard, people assume the perp is of a certain other racial/ethnic group.
