(CNN) -- Hundreds of protesters are expected to converge at the Billings, Montana, county courthouse Thursday, to express their outrage over what they call a lenient sentence for a man who admitted raping a 14-year-old girl.
The protest, organized in part by the National Organization for Women, will call for Yellowstone County District Judge G. Todd Baugh to step down.
The mother of the victim is outraged that a high school teacher who admitted raping her daughter received only a month in prison, while her daughter later took her own life.
As the calls for an appeal grow, the Montana attorney general's office is reviewing the case.
"I was horrified. Horrified," she said. "He broke the law, he confessed, and he got to walk away."
