Andrea Yates

Andrea Yates (born Andrea Pia Kennedy on July 2, 1964) is a former Houston, Texas resident who killed her five children on June 20, 2001 by drowning them in the bathtub in her house. She had been suffering for some time with very severe postpartum depression and postpartum psychosis. Her case placed the M'Naghten Rules with the Irresistible Impulse Test, a legal test for sanity, under close public scrutiny in the United States. Yates's 2002 conviction of capital murder and sentence to life in prison with the possibility of parole after 40 years was later overturned on appeal.

On July 26, 2006, a Texas jury found that Yates was not guilty by reason of insanity. She was consequently committed by the court to the North Texas State Hospital, Vernon Campus, a high-security mental health facility in Vernon, Texas, where she received medical treatment and was a roommate of Dena Schlosser, another woman who committed filicide by killing her infant daughter. In January 2007, Yates was moved to a low security state mental hospital in Kerrville, Texas.
