Ralph Leroy Menzies, 67, is set to be executed Sept. 5 for abducting and killing Utah mother of three Maurine Hunsaker in 1986.

The U.S. Supreme Court has at times spared prisoners with dementia from execution, including an Alabama man in 2019 who had killed a police officer. If a defendant cannot understand why they are being put to death, the high court said, then an execution is not carrying out the retribution that society is seeking.
