She was given a life sentence, and is currently in the Tennessee Prison for Women in Nashville. She will not be eligible for parole until she is at least 67, Mr. Bone said.

Life in Prison

Ms. Brown’s supporters have described her as a model inmate. After getting her G.E.D., she got an associate degree from Lipscomb University, a private Christian college in Nashville that teaches classes at the prison. She hopes to earn a bachelor of arts degree by next year, Mr. Bone said.

State Representative Jeremy Faison, a Republican from Nashville, visited Ms. Brown in 2015 on a friend’s recommendation, and has since been pushing for her early release. They speak about four times per year on the phone, he said.

“I was amazed at the person I met,” he said. “She was kind, intelligent, she had a disposition or presence about her that was just amazing.”

He described Ms. Brown as “extremely remorseful,” but said she also thinks “it was unjust what had happened in her life, and what a 40-year-old man was doing to her.”

Mr. Bone said his client hopes to focus her energy on combating sex trafficking.

“Seldom do you have someone as articulate as she is, with the ability to say: ‘I’ve been there, I’ve done that, and I want to speak out, to let the world know that this is indeed an awful problem,’ ” he said.

But Jeff Burks, who prosecuted Ms. Brown and is now an assistant district attorney in Madison, Ga., told Fox 17 in Nashville on Tuesday that she shouldn’t be considered a victim.
