A Haverstraw man is heading to prison for 1-3 years after pleading guilty to stealing more than $300,000 from two Greenburgh doctors by claiming the funds would be used to finance real estate investments but instead used the money for himself. Former Yonkers city police officer Mario Sasso pleaded guilty to grand larceny, scheme to defraud and criminal tax fraud in Westchester County Court last fall. The Westchester D-A says Sasso also failed to pay more than $10,000 in taxes six years ago.
