McFlurry’s are a super sweet beverage. I’ll bet the woman was having a hypoglycemic attack which is why she desperately craved something sweet. I used to get them, and I would have the feeling, I’ll kill unless I get some food into me immediately. Fortunately I got this under control 40 years ago by strongly limiting the amount of sugar and white flour and rice products in my diet.
Quite possibly you are correct.
That said, the scientist in me suspects that there might have been something else going on in her blood stream. Hopefully she is apprehended in time to do a valid tox screen.
