In the 2000s, Scheper-Hughes investigated an international ring of organ sellers based in New York, New Jersey and Israel. She interviewed several hundred third-world organ donors, and reported that they all felt that they had been taken advantage of, and were often left sick, unable to work, and unable to get medical care. Some of them were tricked into donating organs, and threatened at gunpoint when they tried to resist. Some transplants took place at major New York City hospitals, and Scheper-Hughes said that the hospital personnel knew illegal transplants were taking place. She informed the Federal Bureau of Investigation, which led to arrests several years later. When the events became public, she said that much of the world's illicit traffic in kidneys could be traced to Israel.
