Q: Context : Stacey Ann Lannert (born May 28, 1972, St. Louis, Missouri is an American woman convicted of the murder of her father, Tom Lannert, when she was 18 years old. She testified that he had sexually abused her since she was 8 years old. Sentenced to life in prison, she served 18 years. On January 10, 2009, outgoing Missouri Governor Matt Blunt commuted Lannert's sentence and that of another woman convicted under similar circumstances. He said, ''After an exhaustive review of the facts in both cases, I am commuting the sentences of Stacey Lannert and Charity Carey, who suffered extensive abuse before they took action against the men who raped them and subjected them to other horrible physical and emotional abuse.'' Lannert's new sentence of 20 years made her eligible for immediate conditional release, and she was released on January 16, 2009. Lannert founded a resource website and non-profit organization, Healing Sisters, to aid women who have suffered abuse. In 2011, she published a memoir about her experiences, Redemption: A Story of Sisterhood, Survival, and Finding Freedom Behind Bars.
