Wow...I could never imagine rifling through my bff's handbag, let alone a coworker or BOSS. I'm glad you reported her to HR...I knew a woman who worked at a hospital and slowly but surely, all the women's purses in the employee room had credit cards stolen out of them. I don't know how the woman thought it couldn't be traced (buying things and sending them to her own house and all), but one of their coworkers was stealing from them. I have no doubt that this woman was attempting to do the same. You're just extremely lucky you caught her in the act...and frankly as a supervisor myself, if I caught someone doing that to my purse (granted, I worked with all men, but still).....they wouldn't be working for me very much longer.
