Final answer:
Sentences for robbery or burglary with a weapon resulting in death can result in life imprisonment or death penalty, but Supreme Court rulings limit death sentences for individuals who did not commit, attempt, or intend the murder, such as in Enmund v. Florida.
Step-by-step explanation:
The sentences for burglary or robbery with a weapon where death resulted can be severe, including life imprisonment or even the death penalty. However, several important Supreme Court cases have set limitations on the imposition of the death penalty. For instance, in Enmund v. Florida, the Court ruled that the death sentence cannot be imposed on offenders who did not kill, attempt to kill, or intend that a killing take place during a felony. Similarly, Ford v. Wainwright prohibits the execution of individuals who are insane. In cases where a defendant did not commit the homicide but was a participant in a felony, like armed robbery, that resulted in a death, the death penalty would not be appropriate under Enmund v. Florida. The scenario provided illustrates a situation where two suspects are involved in a crime with varying degrees of participation, potentially affecting the severity of their sentences.
