Sixteen people, mostly medical workers, were convicted of involvement in an organ trafficking ring and sentenced to between two and five years in jail by a court in Shandong on Friday, mainland media reported. The ring performed illegal kidney transplants at various hospitals and clinics in Jinan, Taian and Feicheng cities since 2014, according to provincial news portal Iqilu.com. The report did not identify the hospitals involved or specify how many transplants had been performed before the ring was busted in May 2015. Instead, it said the trading spanned more than a dozen provinces and municipalities, including Heilongjiang, Inner Mongolia and Chongqing.
