I say:
Make a deal with him in exchange for getting the info about what happened to Mickey....then put him in gen pop.
I wouldn't be opposed. Bring some closure to the family. Family can avoid the pain of re-living it all through a public trial. Avoid the risk that something goes horribly wrong with a trial. Life with NO parole---but like you said, put him in general population. He avoids the death penalty but has to bring Micky home to her family.
