Yep she was attacked in this sadistic manner because she was white.
Actually, there have been quite a few examples of blacks murdering whites this way. Here is one example that is almost totally unknown to most, even those who research hate crimes:
Evelyn Wagner:
“At about 9:00 pm on October 2, Evelyn ran out of gas near her house while borrowing a car. She walked eleven blocks to a filling station carrying a small empty gas can.
On her return, six black teenagers confronted her. They forced her down an alley and behind a building. They beat her up and shouted racial slurs. The teenagers demanded she pour the gasoline on herself. She complied on threat of more violence. One teenager then flicked a match at Evelyn, and she burst into flames. The teenagers walked away in laughter.
Evelyn Wagler tried in vain to roll on the ground and put out the fire. She was receiving second and third degree burns all over her body. Charred and smoldering, with her hair burnt down to her scalp and face
Evelyn Wagler died four hours later. ....’
