TRENTON - (AP) - A New York City man was sentenced to two and a half years in prison Wednesday for what prosecutors say is the first ever federal conviction for illegally selling human kidneys for profit.

Levy Izhak Rosenbaum of Brooklyn pleaded guilty last October to brokering three illegal kidney transplants for New Jersey-based customers in exchange for payments of $120,000 or more. Prosecutors say Rosenbaum would buy organs from vulnerable people in Israel for $10,000 and sell them to desperate patients. He was arrested in July 2009 in a sweeping federal case that became the largest corruption sting in New Jersey history.

Rosenbaum was caught up in the case by an undercover government informant posing as a crooked businessman looking to buy a kidney for a sick relative.

Witnesses presented conflicting accounts of Rosenbaum's actions. Some said he saved their lives while others claimed they felt taken advantage of. Rosenbaum testified that he had come to learn that what he did was wrong, but he thought the cause was good.
