MAPUTO, Mozambique — One day in October 2015, Electerio João’s brother-in-law called him up and asked him to come “work and earn money.” Mr. João, who was 22 at the time, welcomed the opportunity. He was living with his mother in a small mud-brick house in the village of Namina in northern Mozambique. He needed the cash.
But he quickly realized that he was going to be the source of cash, not labor. His brother-in-law, working with three of his friends, tied up Mr. João with a rope and took him to the side of a main road, where they planned to sell him for his body parts.
