To follow the train of thought some of you have begun vis-a-vis the step-father, I noticed from Katelin's FB page she seems to be in a relationship with another woman, which potentially could have been the source of some familial tension. This is also relevant because of the reference to a "roommate's credit card" being her only source of money (it would make more sense to me for a boyfriend/girlfriend to share or lend a credit card to someone else than just a plain old "roommate). I wonder if "roommate" was how the family referred to her girlfriend, which could also indicate a lack of acceptance/point of tension?
