I'd say that whoever applied her ink, wasn't a professional. Someone probably traded a stolen setup to their dealer for some crystal meth and he gave it to a homeless wine-o for 1/2 pack of stale Newports. The wine-o was mugged by MS-13 on his way to pawn the setup and when the cops interfered with their crime, the kit was tossed into the bushes. It sat there unnoticed for several years until that stinky kid with Velcro shoes down the block found it on his way to 7-11 to get a chili dog with extra onions and nacho cheese. Stinky left the kit outside the store and this girl's boyfriend saw it on his way in to rob the place and grabbed it. After a quick trip to see his dealer, he brought it back to the trailer park. Upon consuming half their stash, he and this chick decided to test out the equipment.
At least, that's MY theory...
