Andrea Pia Yates ( Kennedy; born July 2, 1964) is an American woman from Houston, Texas, who confessed to drowning her five children in their bathtub on June 20, 2001. The case of Yateswho had exhibited severe postpartum depression, postpartum psychosis, and schizophrenia leading up to the murdersplaced the M'Naghten rules, along with the irresistible impulse test for sanity, under close public scrutiny in the United States. At Yates' 2002 trial, Chuck Rosenthal, the district attorney in Harris County, asked for the death penalty. Yates was convicted of capital murder, but the jury refused the death penalty option. She was sentenced to life in prison with the possibility of parole after forty years. The verdict was overturned on appeal, in light of false testimony by one of the supposed expert psychiatric witnesses. On July 26, 2006, a Texas jury in her retrial found that Yates was not guilty by reason of insanity. She was consequently committed by the court to the high-security North Texas State Hospital in Vernon, where she received medical treatment and was a roommate of Dena Schlosser, another woman who committed infanticide by killing her infant daughter. In January 2007, Yates was moved to Kerrville State Hospital, a low-security state mental hospital in Kerrville, Texas. Background Andrea Yates was born Andrea Pia Kennedy in Houston, Texas, the youngest of the five children of Jutta Karin Koehler, a German immigrant, and Andrew Emmett Kennedy, whose parents were Irish immigrants. Yates suffered from bulimia and depression during her teenage years, and at age 17 spoke to a friend about suicide. Yates graduated from Milby High School in 1982. She was the class valedictorian, captain of the swim team, and an officer in the National Honor Society. Yates then completed a two-year pre-nursing program at the University of Houston and graduated from the University of Texas Health Science Center at Houston. From 1986 until 1994, Yates worked as a registered nurse at the University of Texas MD Anderson Cancer Center. In summer 1989, she met Russell "Rusty" Yates, a NASA engineer, at the Sunscape Apartments in Houston. They soon moved in together and were married on April 17, 1993.
