Andrea Yates is a former Houston registered nurse who, on June 20, 2001, drowned her five children in the family bathtub during a severe episode of postpartum psychosis. A Texas jury convicted her of capital murder in 2002, but that verdict was thrown out after a prosecution expert was found to have given false testimony. A second jury, in 2006, found her not guilty by reason of insanity. She has lived in a Texas state psychiatric hospital ever since.
Life Before the Killings
By most outward measures, Andrea Yates’s early life was one of steady accomplishment. She graduated as valedictorian of her high school class, completed a pre-nursing program at the University of Houston, and earned her nursing degree from the University of Texas Health Science Center at Houston. From 1986 to 1994 she worked as a registered nurse at the University of Texas MD Anderson Cancer Center.
In 1993 she married Russell “Rusty” Yates, a NASA engineer. The couple’s home life was shaped heavily by the teachings of a traveling preacher, Michael Woroniecki, who urged married couples to have as many children as possible and warned of spiritual damnation for those who fell short. Andrea left nursing to raise the family full time. She and Rusty had five children in seven years: Noah, John, Paul, Luke, and Mary.
A Documented History of Postpartum Psychosis
Andrea’s psychiatric record is central to everything that followed. After the birth of her fourth child, Luke, in 1999, she suffered a severe breakdown and was hospitalized. Doctors identified postpartum depression that had escalated into postpartum psychosis, a rarer condition involving hallucinations, delusions, and a near-total break from reality.
Over the next two years she was hospitalized multiple times. Her records documented suicide attempts, including pill ingestion and self-harm with household items. She was prescribed antipsychotic medication, including Haldol, for recurring psychotic episodes. Between hospitalizations she experienced catatonic states and profound depression that left her unable to care for herself.
Multiple psychiatrists warned the family that another pregnancy would almost certainly trigger a new psychotic episode. Andrea nevertheless became pregnant with a fifth child, Mary, who was born in November 2000. Her condition deteriorated sharply in the months that followed, even with outpatient treatment. By the spring of 2001, the people closest to her could see she was in serious trouble.
June 20, 2001
On the morning of June 20, 2001, Andrea called 911 from the family home at 942 Beachcomber Lane in Houston. She told the dispatcher only that she was “ill” and needed a police officer, then called Rusty at work and told him to come home. When officers arrived, she led them inside. She had drowned all five children, one at a time, in the bathtub. Noah, the oldest, was seven. Mary, the youngest, was six months old. Detectives took Andrea to the police station for questioning.
The 2002 Capital Murder Conviction
Prosecutors charged Andrea with capital murder under Texas Penal Code Section 19.03, which applies when someone kills more than one person during the same criminal episode or kills a child under a certain age.1State of Texas. Texas Penal Code Section 19.03 – Capital Murder The state sought the death penalty, arguing that her actions were deliberate and that she knew what she was doing was wrong.
The defense built its case around her psychiatric history. The prosecution’s sole psychiatric expert, Dr. Park Dietz, testified that while Andrea was psychotic, she still knew right from wrong under Texas law. In March 2002, the jury returned a guilty verdict on multiple counts of capital murder. The court sentenced her to life in prison rather than death, which under Texas law meant a minimum of 40 calendar years before any parole consideration.2State of Texas.

Why the Conviction Was Overturned
In 2005, a Texas appellate court threw out the conviction after finding that Dr. Dietz had given false testimony. On cross-examination, Dietz had told the jury about his consulting work on the television show Law & Order, and described an episode in which a woman with postpartum depression drowned her children in a bathtub and was found insane. He said it had aired shortly before the killings. The implication was that Andrea had used the episode as a blueprint.
No such episode existed. After the guilty verdict but before sentencing, Dietz told prosecutors that the show’s producers had searched all 269 episodes and found nothing matching his description. He acknowledged confusing plotlines with real filicide cases he had consulted on. Prosecutors had already leaned on his account in closing argument. The appeals court found the false testimony central enough to warrant a new trial.
The 2006 Insanity Verdict
The retrial turned on Texas Penal Code Section 8.01, which provides an affirmative defense when a person, because of a severe mental disease or defect, did not know that what they were doing was wrong.3State of Texas. Texas Penal Code Section 8.01 – Insanity The second jury heard from a broader range of mental health experts and reviewed the full scope of Andrea’s psychiatric records. On July 26, 2006, they returned a verdict of not guilty by reason of insanity.
Where Andrea Yates Is Now
An insanity acquittal in Texas does not mean release. The court holds a separate hearing to decide whether the acquitted person has a severe mental illness and poses a danger to others, and if so, orders inpatient commitment.4State of Texas. Texas Code of Criminal Procedure Article 46C.253 – Hearing on Disposition The court keeps jurisdiction for as long as the maximum prison sentence would have run. For Andrea, that is the rest of her life.
In January 2007 she was transferred to Kerrville State Hospital, a low-security psychiatric facility in the Texas Hill Country. There are no armed guards or razor wire. Patients receive therapy, take medication under medical supervision, and live in a structured treatment environment.
Texas law entitles Andrea to an annual review hearing at which a judge evaluates whether she still meets the criteria for continued confinement. Every year since her commitment, her attorney has waived that hearing on her behalf. According to her longtime lawyer, George Parnham, she has consistently chosen to remain in treatment rather than pursue release. As of the most recent available reports, she is still at Kerrville State Hospital.
The Case’s Effect on Postpartum Mental Health Awareness
Before 2001, postpartum psychosis was largely unknown outside the medical community. The Yates case forced it into public view and raised uncomfortable questions about how the healthcare system screens for and responds to severe maternal mental illness.
In 2003 Texas passed what was informally called the “Andrea Yates Bill,” requiring the state Department of Health to maintain a web-based list of professionals and resources for families dealing with perinatal depression. At the federal level, the Melanie Blocker Stokes MOTHERS Act was incorporated into Section 2952 of the Patient Protection and Affordable Care Act in 2010, directing the Secretary of Health and Human Services to expand research on postpartum depression and psychosis and authorizing grants for clinical services.
Two juries heard largely the same evidence about the same woman and reached opposite conclusions. That split is why the Yates case remains the reference point whenever the conversation about severe mental illness and criminal responsibility resurfaces.
