While most people assume that only women are victims of sex trafficking, it turns out that a small yet silent group of men are often victims of this inhumane trade, according to human rights officials.

Sunday’s story, though rare, isn’t unique. Sam had tried to escape, his executioner explained. Two days later, Sunday says, he watched, trembling and wearing nothing but underpants, as a man tied Sam to a chair and asphyxiated him with a plastic bag. He hung up on his mom and jumped into his new friend’s car with another Ugandan boy his age named Sam. Struggling for money, he couldn’t believe his luck when a stranger named Charles offered him a job in his brother’s factory in Nairobi. He was 24 and studying tourism in Kampala, the capital of next-door Uganda. Bekunda Sunday still remembers the pride in his mom’s voice when he told her he’d landed a job in Kenya.
