The setting-on-fire could be a domestic dispute or a fight among former friends, but the unspecified “racial slurs” spraypainted on her car take the probability that she did it herself (oops) into the 95% range.
How would a random attacker know which car was hers, and just happen to have spray paint to hand? Some people seem to imagine that armed robbers and loser thugs coincidentally always have the right color of spray paint with them, and plenty of time to carefully, in the dark, spraypaint just the most offensive thing.
"KKK" on her car has been confirmed. I'm skeptical.
I think it’s more likely that she knew those attacking her and that it was planned and NOT a “random attack”. I would hazard a guess that she knows EXACTLY who did this to her and why, but she is afraid to name names - obviously because if they were ready to burn her alive before what would they do if she “ratted” them out??? I have a hard time believing someone would set themselves on fire for a hoax... It’s a little too dangerous unless the point was to actually commit suicide.
The vague description of her attackers - to the point where she doesn’t have a clue what “race” they were sounds an awful lot like the descriptions given by victims of gang violence who are terrified, and know the police won’t be able to protect them.
