Elizabeth Ann Duncan
Elizabeth Ann Duncan, also known as Ma Duncan (about 1904 – 8 August 1962), was an American murderer. She was convicted of orchestrating the murder of her daughter-in-law in 1958. She was the last woman to be executed in California before the United States Supreme Court suspended the death penalty under its 1972 ruling in "Furman v. Georgia".

Elizabeth Duncan was convicted of hiring 28-year-old Augustine Baldonado and 23-year-old Luis Moya to murder her daughter-in-law, Olga Duncan, who was seven months pregnant at the time. The three prisoners were executed the same day in the gas chamber at San Quentin State Prison on August 8, 1962.
