The study was conducted in the suburbs of a major metropolitan area in the mid-Atlantic region. None of the former jurors had served on a capital case. Participants received a booklet-style questionnaire that described a murder of a store clerk in a robbery, as well as the subsequent court proceedings, in which the defendant was found guilty of first-degree murder. The defendant's age (10, 15, 16, or 19) and level of remorse were varied. Results revealed that a large percentage of participants voted to execute the defendant in each case, but the defendant's age and the participant's attitude toward juvenile culpability significantly predicted the likelihood of execution.
