I looked at the Iowa DOC quick facts page and found that the State prison population is around 8400, and over half are violent offenders. The system is overcrowded by about 1000. Less than 800 inmates are serving terms of more than 40 years. It costs $92/day to maintain an inmate. In a state that is 95% white, the racial make up of the prison population is 67% White, 25% Black, and 7% Hispanic.
CR may be too high profile to be safe in GenPop, as there are such things as status killings. Consider what happened to Jeffrey Dahmer. Nor do I think that CR's anger management skills will endear him to anyone. Depending on how bad the backlash is on the outside Latino community from his actions, I don't think that the inside Hispanic pop will be too happy with CR, and he might not be able to find safe harbor with any of the main groups. I think that life without parole in Adminstative Segration is a start.
Though, as the Iowa penal system is over capacity, one could wish that they pay Louisiana to hold CR for them at Angola. Even today, the new guys start working in the prison farm fields, working crops the old fashion way, in the hot Delta sun, and may work on the farms for years before getting a better job. But that is just wishful thinking on my part!
