A former Nassau County judge who admitted to laundering money for mobsters and dealing in “stolen” diamonds was sentenced Friday to 33 months in prison.

David A. Gross, who was elected a district judge in 1999, billed himself as a “law and order” judge and showed no visible emotion as Eastern District of New York Judge Arthur D. Spatt handed down the sentence and admonished the disgraced judge for abusing the public’s trust.
