Just catching up on this so not sure if this has been brought up already. Because he had initially "confessed", albeit a false/coerced confession, do you think there's any way he could go after the state/county for false imprisonment? So sad so much of his life was wasted being incarcerated because his mental capacity was taken advantage of.. JMO.
I believe if it stands that his confession was against his constitutional rights and basically coerced, he will have a case. JMO
