The man holding Yafimau against his will was Roini Shimshilashvili, a former kickboxer who was an enforcer for an international organ-trafficking ring, according to evidence gathered by police in Kiev. Yafimau says that when he pleaded with Shimshilashvili to let him get out of the deal and go home, the big man sliced the air with Thai-boxing moves and threatened him.

“He said if I didn’t go through with it, he would leave me in Ecuador and kill my family,” Yafimau says.

Doctors removed Yafimau’s left kidney in July 2010 and transplanted it into an Israeli woman, according to the Kiev police investigation. On the plane back to Belarus, on the western border of Russia, Shimshilashvili told Yafimau that if he wanted to live, he shouldn’t talk to police.
