Law question here,murder,death penalty?

I have been studying criminal justice and have a degree. You don't need fingerprints or witnesses sounds like they had substantial evidence in the hair found. Those hairs probably hurt his case and tied him to the scene. Everyone convicted of first degree murder has a right to appeal and it will go to the appeals court. You can do that a few times but most of time the appeals court will not overturn the verdict if the evidence is strong enough for a conviction. He will probably sit on death row for a very long time and die of natural causes before they would put him to death. All anyone can do now is pray for his soul. God Bless.
