Things like choice of prison, terms of captivity like protective custody or a more lenient AdSeg, allowing visits with his child and her mom, might make for a Murder One plea. But I don't think the State will go with Murder Two, as their case is too strong.
MSM is reporting a NeoNazi group making robocalls into Iowa calling for the death of all Latinos in the US. Depending on the backlash that MT's murder causes problems for the Latino communiy, CR may have a very hard time in prison, as the Latinos may not have his back, and the Aryians may well want a piece of him, and everyone else may not want to get involved.
