Mary Frances Creighton

Mary Frances Creighton (July 29, 1899 – July 16, 1936), was a housewife, who along with Everett Applegate, a 36-year-old former American Legion official, was executed in Sing Sing Prison's electric chair, Old Sparky, for the poisoning of Applegate's wife, Ada, in Baldwin, New York on September 27, 1935. She had passed out before the execution, and was executed in an unconscious state.
While living in Newark, New Jersey, Creighton was also suspected of poisoning her mother in-law, Anna Creighton, in 1920, her father in-law, Walter Creighton, in 1921, and her younger brother, Raymond Avery, in 1923. Creighton and her husband, John, were tried for Raymond's death in 1923, but were acquitted due to a lack of witnesses. The Anna Creighton murder trial, which was held in 1923 as well, also ended with Creighton being acquitted, again due to a lack of witnesses, and also due to the testimony of toxicologist Alexander Gettler, who found only a trace amount of arsenic in Anna Creighton's system.
After her arrest for the murder of Ada Applegate, who Creighton claimed to have poisoned so that her fifteen-year-old daughter, Ruth, who she had been pimping out to Mr. Applegate, could legally marry, she repeatedly confessed to and denied killing both Anna and Raymond.
