from the picture I am betting on HOAX
I was willing to believe it, but the BACKWARDS B is a dead giveaway
1) Picture yourself writing it on your face and how it would look, now try writing it so the letter is correct- you can easily make a backwards B on your own face, a correct B is hard.
2) Now picture the criminal writing ON you- why would HE write it backwards?
IF she were already on the ground and the aledged assailant bent over her on his knees from above her head he would be carving a normal "B" that appears backward when we view her face normally.
Please see number #119.
