It turns out Maura was considering ending things with Billy. Seems she had gotten very close to a nice, ambitious young man at UMass and her friends were pushing her to drop Rausch for this new guy. It was a relationship she had to keep secret at the time for a good reason.
I have the man's name but I'm waiting for him to respond before I go into it too much.
I would very much like to speak to anyone who knew Maura at UMass. Please contact me at firstname.lastname@example.org
