A former inmate who became pregnant at an Illinois prison alleges a group of guards repeatedly raped her while she was serving seven months for writing a bad check, The Chicago Tribune reported on Tuesday.

The unidentified woman, a former beauty pageant winner, filed the lawsuit on Monday against several members of the staff at the Dwight Correctional Center, according to the Tribune.

"You don't know if they're going to kill you," the woman told the paper. "I did not know what was going on with my own body."

The ex-prisoner said she was not allowed to do work detail or walk short distances because of her obstructive pulmonary lung disease, which enables her to use only 30 percent of her lung capacity.

During the alleged sexual assaults, the Tribune reported, she was ushered into the staff bathroom, along with her oxygen generator, where she claims she was raped.

She alleges she was raped at least 29 times while serving time, during which the only men she had contact with were corrections officers, according to the newspaper.

When she was released in June 2006 she already was 14 weeks pregnant.

She was expected to testify against her attackers this week.
