Who lived in New City, NY *2 UPDATES*

What you see here is a screen cap from the episode of Disappeared that showcases Maura's case. It's a quick shot of Maura's cell phone bill (which was paid by Bill Rausch's family). Some late calls to a number in New City, NY in the days leading up to her disappearance.
Anyone have a clue?
**UPDATE**Several readers have pointed out that New City, NY is not far from West Point. So, it's possible it could be a classmate, her sister, Julie, or even Billy. Though if they're on the same plan, I'm assuming that would be apparent.
**UPDATE 2**Some readers have pointed out the 3:40 am phone call Maura made the day she broke down at work. That appears to be a call to the Domino's in Hadley, which is open till 4 a.m.
