Maybe her grandmother is magic and she's power hungry. That taser (or as you all call it "stun gun") is possibly extracting the magic.

Or my theory linking to Owen, is that she is (or he is) a journalist that is writing a story on Storybrooke. Hence why Owen has been taking photographs and recording events. Then if you want to tie this into the theory of her grandmother being magic, it's possible that she (the grandmother) was from The Enchanted Forest or a neighbouring magical land, and something terrible happened to her causing her supposed death. Tamara is maybe researching this, possibly continuing her unmentioned mother'/father's work - and has become power hungry.

I dunno! Just some of my crazy thoughts!
