Jackson was moved from a federal prison camp in Alabama to the halfway house in March, after spending about 17 months in federal prisons in North Carolina and Alabama.

He was able to get six months knocked off his original sentence for completing a substance abuse treatment program while behind bars. He also received credit for good conduct.

While in prison, he also attended daily therapy sessions to help him with bipolar disorder and depression. He said he still suffers from depression, and is continuing therapy and medication to manage his symptoms.
