NEW YORK (AP) _ A former American Cancer Society official has been convicted of aiding and abetting tax evasion in a scheme that prosecutors said generated nearly $4 million in phony write-offs.

A U.S. District Court jury deliberated more than three hours over a two-day period before deciding Friday that Miriam Grubard was guilty of 33 counts of aiding and abetting tax evasion and one count of conspiring to defraud the Internal Revenue Service.

Mrs. Grubard, 67, of Lynbrook, faces up to five years in prison on the conspiracy count and three years on each of the 33 tax counts. Sentencing has been scheduled for June 2.

According to testimony, Mrs. Grubard, former executive director of the society's Manhattan unit, arranged to have wealthy people write out large checks to the society. The donors would claim the entire amount as a tax deduction, but Mrs. Grubard would arrange to kick back 90 percent of it in cash or in other forms, such as gift certificates to swank Fifth Avenue stores.

Mrs. Grubard, who was indicted last December after other Cancer Society officials uncovered the scheme, did not profit personally from the fraud, according to the government.

A dozen donors who took false tax deductions have pleaded guilty to various charges.
