The indictment alleges that Bagley met the woman when she was 16 and a runaway and persuaded her to move into his trailer with promises of a "great life" and a future as a model and dancer.

She got her own room, furniture and TV, and Bagley began giving her drugs, showing her pornography and sexually abusing her, prosecutors said.

When she turned 18, he persuaded her to sign a 'sex slave contract," which he said bound her to him for life, prosecutors claim.

Bagley "beat, whipped, flogged, suffocated, choked, electrocuted, caned, skewered, drowned, mutilated, hung and caged" the girl "to coerce her to become a 'sex slave,'" the indictment says. It adds that he tied her up and hung her in the air, locked her in a dog cage and used staples, nails and a sewing needle and thread during torture sessions too violent to describe.

In 2005, Bagley began boasting online that the girl was his slave and could be tortured during online sessions or in person, the indictment says.

Henry, Stokes, Noel and Cook gave Bagley cash, cigarettes, computer equipment, sadomasochism videos, coats and meat in exchange for access to the girl, the indictment says.
