If it is her then she seems to have made a decent way of life for herself.
I'm not saying she was involved with Chris's crimes but she was bound to know that he was a dodgy guy
In Murder Machine it says Roy gave her 10K after Chris died, and she wouldn't answer questions from the NYPD and other law enforcement. I think this has to her, there are only two people in the US with the name Stephanie Rosalia, and the other one isn't from NYC and is too young to be connected to Chris. It seems the place in NYC where Chris had his home that was being renovaited when he died is now one of the most expensive and prestigious neighborhoods in NYC, so he wasn't no dummy. If Chris wasn't so greedy and nuts he could have build a nice niche for himself as a Jewish associate, ala Burt Kaplan.
