Anne Marie O'Hara
From Tardis Wiki, the free Doctor Who reference
Anne Marie O'Hara was the wife of Mathew O'Hara and the mother of Patrick O'Hara. She had been trained as a mathematician but abandoned research to study music. She found about her husband's plan to save humanity, including their son, from the collapse of Earth's environment by uploading copies of their minds into computers, and when she expressed her outrage to him, he killed her by poisoning her drink.
