A Chicago based woman sued her wealthy husband for divorce claiming she spent the last six years as a terrified slave enduring sadomasochistic assaults.

Kimberley O'Brien, 45, has also filed a separate suit against Kevin Anderson, 50, accusing him of cheating her on joint business dealings, photographing her bound-and-gagged body, and causing a wrongful death by forcing her to abort a child against her will.

Anderson denies all of her allegations, but neither he nor his lawyer would speak to the Chicago Sun-Times for an interview.

The United Press International reports Anderson has one domestic violence-related conviction on his record from Oct. 4, 2005, in which he originally was charged with battery. In March, he pleaded guilty to the lesser charge of disorderly conduct.

O'Brien said Anderson wields substantial political power in Wisconsin and Minnesota, where he runs various businesses, and said that's why she filed the lawsuits in Chicago.
