About the sentencing itself, Baugh said he would file an addendum to the case file to "better explain" his rationale.
The case began in 2008 when Cherice, then 14, was a student at Billings Senior High School and Rambold, then 49, was a teacher.
Hanlon claims Rambold's "pre-sexual grooming" of her daughter led to the pair having sex.
School officials learned of the relationship, and Rambold resigned.
Later that year, authorities charged Rambold with three counts of sexual intercourse without consent.
"It's not probably the kind of rape most people think about," Baugh said. "It was not a violent, forcible, beat-the-victim rape, like you see in the movies. But it was nonetheless a rape. It was a troubled young girl, and he was a teacher. And this should not have occurred."
As the case wound its way through the legal system, Cherice committed suicide. She was a few weeks shy of her 17th birthday.
"As a result of the sexual assault and its aftermath, (Cherice) experienced severe emotional distress, humiliation and embarrassment and fell into irreversible depression that tragically led to her taking her own life on February 6, 2010," Hanlon said in a complaint filed against Rambold.
Hanlon told CNN the relationship was to blame for her daughter's death.
"Well, it definitely had something to do with it," she said. "A teenager's whole life is about school and their friends, and he turned everyone against her."
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 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.
Rambold admitted to one of the rape charges.
But the ex-teacher fell short of the agreement.
"He had some contacts with nieces and nephews in a family setting and other adults were present," Baugh said.
He also had relationships with women that he didn't tell his counselors about.
"That is a violation from his deferred prosecution so he was dropped from the plan."
As a result, the case was revived in December 2012.
