A Westchester woman is facing more than a decade in prison after pleading guilty to stealing nearly $1 million from her victim while serving as a part-time personal assistant over the span of five years. Westchester County District Attorney Anthony Scarpino said Tuesday that Yonkers resident Joann Perrino, 60, pleaded guilty to second-degree grand larceny after utilizing her victim’s bank accounts for her own benefit, totaling $987,428.87 between January 2009 and May 2014.
