Modifies provisions relating to trial procedures for murder in the first degree

HB 2186 changes how first-degree murder trials are conducted when the death penalty is an option. It requires a two-stage trial: first to determine guilt, then to decide punishment. If the defendant is found guilty of first-degree murder without a death penalty waiver, the second stage focuses solely on sentencing, with life imprisonment without parole mandated if the court finds intellectual disability, no aggravating circumstances, or sufficient mitigating evidence outweighing aggravation. This bill affects defendants charged with first-degree murder in cases where the death penalty is sought, applying only to offenses committed on or after August 28, 2001.
