I doubt they would, but they probably do have access to her accounts that shes using, so they can probably see when shes making the transfers. Seriously, I would call your local LEO NOW, and dont even tell her(well you should tell her, but if shes refusing to quit, shes a dumb, and naive. She will likely get no charges pressed against her unless she helps them figure out whos, hows, and whens. The sooner you get her to stop, and report it, the sooner you do that, the better off you both will be(you can be counted as an accessory to it). Also, because she is using her account, he is at risk of getting federal felony charges and prison time if she does not stop.
