My guess is she probably had a stash in the car, and when she was being pulled over, she swallowed it. A victomology adherent with a huge, racial chip on her shoulder, in addition to being an unstable individual with suicidal tendencies. Of course, none of that will satisfy the Canadians & their Communist backers such as Hillary.
So who put a plastic bag in her cell? Test it for marijuana.. Who knows?
Or she was a drug mule and was transporting a large quantity internally. It would explain whey she was so agitated about being stopped and given a traffic warning.
