BILLINGS, Montana (CNN) -- Stacey Dean Rambold, a former high school teacher who served a month-long sentence for raping a 14-year-old girl, was released Thursday from a Montana jail, a state Department of Corrections official told CNN.
The former high school teacher was released from Montana State Prison in Deer Lodge between 9:30 and 10:30 a.m. local time, according to Judy Beck, the corrections official said.
Rampold's lenient sentence and the judge's comments about his victim sparked national outrage and protests.
He won't be a free man exactly; he's on probation for the next 14 years, 11 months.
The victim's mother is hopeful that will change.
"(Judge G. Todd Baugh) made a mistake and I'm disappointed, (31) days, that's outrageous, but the Montana Supreme Court stepped in. Hopefully they'll make it right," said Auliea Hanlon, whose daughter, Cherice Moralez, committed suicide before Rambold went to trial.

Victim's mom to judge: You were wrong
Prosecutors have appealed the sentence -- saying it is illegal -- to the high court.
On Tuesday, the Montana and Pennsylvania chapters of the National Organization for Women and an activist group called Ultraviolet filed a complaint with a judicial review board, CNN affiliate KULR reported. More than 140,000 people signed accompanying petitions, the groups said.
"If we can't get him removed from this, there is something wrong with the system, and I know people in the state will work to not get (Baugh) re-elected (next year)," said Marian Bradley, president of Montana NOW.
The case drew widespread attention when Baugh imposed a one-month sentence on Rambold and made controversial comments about the victim, saying she "seemed older than her chronological age" and she was "as much in control of the situation."
Rambold admitted raping the girl in 2008 while she was 14 and he was her teacher at her high school. Moralez took her life shortly before her 17th birthday.
The judge later apologized for his comments, and earlier this month tried to revisit his sentence. But the state Supreme Court barred him from a new ruling, saying he didn't have the legal standing to change a sentence.
Baugh said he didn't realize at first that the minimum sentence should have been two years.
Baugh's secretary said Wednesday the judge had no comment on Rambold's release.
Hanlon told CNN's Anderson Cooper that she wants to avoid Rambold.
"I never saw him until we were in a courtroom all those years," she said. "I hope I never see him (again)."
Defense attorney Jay Lansing had no comment on the case, but has said his client contends the sentence imposed is lawful and appropriate.
The legal process
With Cherice's death, the prosecution entered into what is known as a "deferred prosecution agreement" with Rambold.
This meant that all charges against Rambold -- who admitted to one of the rape charges -- would be dismissed if he completed a sex-offender treatment program and met other requirements. One of them was to have no contact with children.
But the ex-teacher fell short of the agreement and prosecutors asked Baugh last month to sentence him to 20 years.
