Rabbi Levy Rosenbaum is accused of taking part in a worldwide scheme that would buy kidneys from poor people in such areas of the world as India, Africa, and Latin America, find matches for the kidneys, then sell them. And profits were huge. They would only pay the person $1,000 for the kidney, then resell it for upwards of $150,000. The operation is then performed in another country, where no questions are asked about where the kidney came from.
