A southwest Missouri man was sentenced to 20 years in federal prison for keeping a young woman as a sex slave for six years.

Forty-six-year-old Edward Bagley was sentenced Wednesday after a federal court judge in Kansas City accepted a plea agreement. He pleaded guilty in January to one count of using an interstate facility to entice a minor into illegal sexual contact.

Bagley, of Lebanon, Mo., originally faced 11 federal charges. He was accused of enticing an underage girl to be his sex slave, torturing and mutilating her, and allowing others to view the torture sessions.

Bagley and his wife, Marilyn, said the woman voluntarily engaged in bondage and sadomasochism after she turned 18.

Marilyn Bagley and four other men are also scheduled to be sentenced this week.
