BILLINGS, Mont. — A former Montana high school teacher due to be released today after serving a 30-day prison sentence for raping a 14-year-old student is “still skating” justice six years after the assault, the victim’s mother said.

Stacey Rambold, 54, will leave the Montana State Prison in Deer Lodge after completing the term handed down by District Judge G. Todd Baugh of Billings last month for the 2007 rape of Cherice Moralez.

The sentence drew protests for being too lenient and outrage over comments the judge made that appeared to pin some of the blame on Moralez.

Tears streamed down Auliea Hanlon’s face as she described the emotions that have at times overwhelmed her since a church counselor her daughter confided in first told Hanlon about the rape. Moralez committed suicide in 2010 before Rambold went to trial.

“I figured he’d be fired, go to jail, and she would be vindicated, and that would be the end of it,” Hanlon said Wednesday. “Instead, here it is six years later, still going on, and he’s getting out. ... He’s still skating.”

State officials say Rambold must register as a sex offender and will remain on probation as prosecutors appeal the case to the Supreme Court in hopes of sending him back to prison for a longer term.
