A former official of a social service agency that serves the poor and an ex-owner of printing shops have pleaded guilty to larceny charges in the theft of more than $1 million from the agency, federal prosecutors said Monday.

Sandra Naclerio, 65, and Milton Greengas, 69, both of West Haven, were charged last September with defrauding the Community Action Agency of New Haven.

Naclerio was the agency’s finance director. Greengas is the former owner of printing businesses in the area.

State prosecutors said the pair stole money from the agency for five years by submitting false invoices for office supplies that were never delivered. Authorities said they focused on more than 150 checks payable to Greengas by the agency.

The checks were authorized by Naclerio, prosecutors said.

The phony invoices were for nearly two million forms and envelopes and for enough business cards to supply the entire state Department of Social Services, prosecutors said.

An audit for DSS in March detected an unusual amount of money that was to have been spent on office supplies. The large amount of supplies could not be located at the agency’s offices.

The agency serves nearly 18,000 low-income residents in the greater New Haven area, providing Meals on Wheels, transportation and heating assistance.

Sentencing is scheduled for May 6 in New Haven Superior Court.
