What Happened to My Missing Girl?

I went to a fairly small Christian college out here in the Midwest. Everyone knew everyone, and I had this really close knit group of friends. We'd all stayed in the same dorm and by the end of our freshman year, we were practically sisters. After like three weeks of not hearing from her and having her duck my calls, I decided to ask one of her friends if there was anything I should know about. That's when she told me that the same girl hadn't been replying to any of her texts either.
