Time for new charges against all four individuals involved in the attack. 2nd Degree Murder for the principal individual who swung the hammer, accessory to 2nd Degree Murder for the others. If not that, at the very LEAST it should be Manslaughter with aggravating circumstances and the other three should be charged with accessory to the manslaughter. Make it straight time with no parole for any reason. Send them in for 10 to 20. Damn shame you can't put this kind of scum in for Hard Time busting rocks all day in the sun, or working on fixing railroad tracks. It's sad Mr. Nelson wasn't armed and trained in how to use weapons in self-defense. He might be the one still enjoying being outside in the sun, instead of the criminals that sentenced him to a slow downhill course to death.
