The Tennessee Supreme Court said Thursday that Cyntoia Brown, a Nashville woman serving a life sentence in prison for a murder she committed at 16, could be eligible for release after she serves 51 years in prison. The statement gave pivotal context to Brown’s fight to convince a federal appeals court to overturn her sentence. Brown, now 30, has been locked up since 2004, when she was convicted of shooting 43-year-old Nashville real estate agent Johnny Allen. Her legal team launched a challenge to her life sentence in the federal court system, pointing to a 2012 ruling from the U.S. Supreme Court saying that giving juveniles life sentences without parole was cruel and unusual in most cases. Cyntoia Brown can be released after serving 51 years in prison, Tennessee Supreme Court decides She had a miserable beginning and is going to have a miserable end.
