(CNN) Cyntoia Denise Brown, a woman serving a life sentence for killing a man who bought her for sex when she was 16 years old, has been granted clemency, the Tennessee governor's office said Monday.

Brown, 30, will be released to parole supervision on August 7 after serving 15 years in prison, Republican Gov. Bill Haslam's office said in a statement.

"This decision comes after careful consideration of what is a tragic and complex case," Haslam said.

"Cyntoia Brown committed, by her own admission, a horrific crime at the age of 16. Yet, imposing a life sentence on a juvenile that would require her to serve at least 51 years before even being eligible for parole consideration is too harsh, especially in light of the extraordinary steps Ms. Brown has taken to rebuild her life. Transformation should be accompanied by hope."

Brown's case drew the attention of several high-profile advocates including a US congressman, several Tennessee lawmakers and a number of A-List celebrities. Comedian Amy Schumer, reality star Kim Kardashian West and actress Ashley Judd were among those who called for Brown's clemency.

I encourage and plead with my Tennessee Governor @BillHaslam to grant #Clemency4Cyntoia. Cyntoia Brown was a victim of child sex trafficking, raped and forced into paid sexual exploitation to stay alive. She deserves our empathy and your mercy. — ashley judd (@AshleyJudd) December 17, 2018
