Grant Clemency to my 33yr old friend Aaron Mcfarland, In jail for being wrongfully convicted

My friend lost all his freedom at the age of 14yrs old. He was was wrongfully convicted of a crime in which he had no involvement. The justice system has failed him because they had did a gun residue kit on him and they never presented it in court because they lost it. He paid his dues and he's not a threat to society. He served 19 yrs on a life sentence. His family is trying to help him re-enter into society so he can finish living his life. This is his first charge and he has never been in any trouble. At the time he wasn't able to read and he didn't understand how the justice system worked. They have no evidence at all. His grandmother had forced him to sign a confession because she felt threatened and intimidated by the officers. Please help me bring an innocent man home. God bless!!!!
