In a rural stretch of Bibb County in central Alabama, past pine forests and gravel roads, deputies uncovered what a sheriff called the most disturbing child abuse case he's seen in his 33 years of working in law enforcement. Inside a concrete bunker near a home, at least 10 children were harmed as part of what the Bibb County Sheriff's Office described as a criminal operation involving sex trafficking, torture and the theft of innocence. Most of the victims were between 3 and 10 years old; one was 15, officials said. At a news conference on Wednesday, Sheriff Wade said seven people, including family members and parents, were charged in connection with the trafficking operation in Brent, Ala., a city of 2,600 people about an hour south of Birmingham, where children were harmed in the bunker's underground structure.
