Just give him the original sentence for the manslaughter conviction. 12 1/2 years.
From the article...
“According to court records, the state’s Supreme Court ruled to reverse the third-degree murder conviction and send the case to district court, where Noor will be re-sentenced for his second-degree manslaughter conviction. He was originally sentenced to 12½ years in prison.”
THe max penalty for second degree manslaughter is ten years. My prediction is they'll sentence him to time served and he'll be home by Christmas.
