Abolishes the death penalty and specifies that any person sentenced to death must be sentenced to life imprisonment without parole

HB 843 abolishes the death penalty for first-degree murder convictions in Missouri, requiring courts to sentence offenders to life imprisonment without parole instead. It directly affects individuals convicted of first-degree murder under Missouri law (RSMo § 565.004), replacing the death penalty option with a mandatory life sentence. The bill repeals existing statutes allowing the death penalty and mandates that any current death sentences be automatically converted to life imprisonment without parole. This change applies to all future convictions and existing cases where a death sentence was imposed but not executed.
