Provides that sentence for commission of certain provisions of murder in the first degree is death or life without parole

This bill (A 5165) changes sentencing requirements for certain serious crimes in New York. It mandates that defendants convicted of specific types of first-degree murder (as defined in sections 125.27(i)-(iii) of the penal law), aggravated murder, or certain terrorism/chemical weapon offenses must receive either the death penalty or life imprisonment without parole. For other first-degree murder convictions, the court must choose between death, life without parole, or a standard class A-I felony sentence. The bill also specifies that individuals convicted of murder in the second degree under defined circumstances must receive life without parole. These changes apply directly to defendants convicted of the listed offenses in New York State.
