A coyote reveals how he smuggled migrants into the US through border sewers in exchange for $6,000. Kevin Noe Campos, 20, from Mexico, made the revelations in a US court after being found guilty of human trafficking.

He faces up to 10 years in prison and a possible $250,000 fine. In the past, human traffickers have advertised their services on Facebook, for as little as $4,500 per person. The sewer pipes connecting the United States and Mexico are fitted with grates to prevent people from passing through them.
