On our tour of Christian churches in Congo's capital city of Kinshasa, we saw Pastor Ngoma Madilu Orlain accuse two sisters, Sarah, 13, and Lufuakenda, 9, of being witches -- with their father, Albert Kanza, looking on.
As the terrified sisters begin to cry, their father remains silent.
"I believe she is a witch," Kanza told ABC News. He told us that he trusts the pastor and that in his mind, there can be no other explanation for his money and health problems.
Once a child is accused of witchcraft, the next step is often exorcism -- a casting out of demons. The ritual can be tantamount to torture. We watched as Tshombe poured hot candle wax on the stomach of a clearly emaciated, 11-year-old girl named Noella.
Kneeling in front of a wooden cross, the pastor and his aides held the girl down as the pastor pretended to pull demonic flesh out of her. Noella was screaming in pain.
It appeared to be a cheap, cruel magic trick, but the crowd, including the girl's mother, appeared to believe.
"It had to happen this way because the child is accused of witchcraft," she told ABC News.
The ceremony does not come cheap. Tshombe was charging $50 -- an exorbitant cost in a country where the average annual salary is $100.
He insisted to us that Jesus Christ would approve of his actions.
"I don't do it for money. I do this because the Holy Spirit gave me the gift to cure," he told ABC News. "If I were a liar, you wouldn't see so many people here. That proves that I am not a charlatan."
As cruel as Tshombe is with the children in his church, exorcisms can purportedly be exponentially worse. There are reports of children being beaten, burned, starved and even murdered -- sometimes by members of their own family.
When we find Orlain forcing a little girl to expel evil spirits through an enema, involving a potion made by boiling a supposedly magical wood, he, like Tshombe, is unapologetic.
"Christ chased away evil spirits. That's what we today would call witchcraft," Orlain said.
Even after a child endures an exorcism, the ordeal is often far from over. Many are said to be permanently tainted in the eyes of their family that they're kicked out of the house.
Life for girls accused of witchcraft is especially horrific. Critics say they are often raped, abused and forced into prostitution.
Many of these girls now have children of their own. We saw them leaving the babies on the side of the road to sleep at night while they went off to turn tricks.
While there are dozens of organizations working to help kids accused of witchcraft, many activists complain that the Congolese government is not doing enough to address the problem.
ABC News took our evidence directly to a senior government official, Theodore Luleka Mwanalwamba, who heads a special commission to protect children, including those accused of witchcraft in the Congo. He said it's illegal to accuse a child of witchcraft -- unless you have proof.
The government official explained that witchcraft is part of the country's traditional belief system. He says it's possible for a child to be a witch, "if a child has big eyes, black eyes or a bulging tummy."
