“if he kills a black girl and leaves her in the street I will assume he is race neutral until then I would be suspicious that this might have been part of the motivation”
I see. I’d be MUCH more likely to assume that the perp picked out somebody who looked like they had money and would be easy prey.
if robbery was the motive he would have robbed her, he went ahead and killed her and judging from the fact that he did not hide his face from the camera I doubt that it was to prevent her from IDing him
