Andrea Yates

Dr. Lucy Puryear, an expert witness hired by Yates's defense team, countered their contention regarding the administration of her antidepressants, saying the dosages prescribed by Dr. Saeed are not uncommon in practice and had nothing at all to do with her re-emergent psychosis. She suggested rather that her psychosis returned as a result of the Haldol having been discontinued by her doctor two weeks earlier. The oral form of haloperidol (Haldol) takes 4–6 days after discontinuation to reach a terminal plasma level of under 1.5%—a medical standard for "complete" elimination of a drug from the body.

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 North Texas State Hospital, Vernon Campus, a high-security mental health facility 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, she was moved to a low-security state mental hospital in Kerrville, Kerrville State Hospital.

On July 26, 2006, after three days of deliberations, Yates was found not guilty by reason of insanity, as defined by the state of Texas. She was thereafter committed to the North Texas State Hospital–Vernon Campus. In January 2007, she was moved to the Kerrville State Hospital, a low security mental facility in Kerrville, Texas.

According to trial testimony in 2006, Dr. Saeed advised Rusty, a former NASA engineer, not to leave Yates unattended. However, he began leaving her alone with the children in the weeks leading up to the drownings for short periods of time, apparently to improve her independence. He had announced at a family gathering the weekend before the drownings that he had decided to leave her home alone for an hour each morning and evening, so that she would not become totally dependent on him and his mother for her maternal responsibilities.

In the aftermath of her 2006 retrial which resulted in an insanity verdict, television journalist Chris Cuomo reported on ABC Primetime that: "[Andrea Yates's] delusions were fueled by the extreme religious beliefs of a bizarre, itinerant street preacher named Michael Woroniecki  ..." Both Rusty Yates and Michael Woroniecki have rejected these accusations.

On January 6, 2005, a Texas Court of Appeals reversed the convictions, because California psychiatrist and prosecution witness Dr. Park Dietz admitted he had given materially false testimony during the trial. In his testimony, Dietz had stated that shortly before the murders, an episode of Law & Order had aired featuring a woman who drowned her children and was acquitted of murder by reason of insanity. Author, and later Yale University lecturer, Suzanne O'Malley, was covering the trial for O: The Oprah Magazine, The New York Times Magazine and NBC News. She had previously been a writer for Law & Order and immediately reported that no such episode existed; Two years later, in 2004, Law & Order: Criminal Intent did air the episode "Magnificat", based in part on Yates's case. The appellate court held unanimously that the jury might have been influenced by Dietz's false testimony and therefore a new trial would be necessary. On January 9, 2006, Yates again entered pleas of not guilty by reason of insanity. On February 1, 2006, she was granted release on bail on the condition that she be admitted to a mental health treatment facility.

According to Dr. Moira Dolan, executive director of the Medical Accountability Network, "homicidal ideation" was added to the warning label of the antidepressant drug Effexor as a rare adverse event, in 2005. Yates, she said, had been taking 450 mg, twice the recommended maximum dose, for a month before killing her children. Dolan reviewed her medical record at the request of Rusty. "Yates had been prescribed Effexor in varying doses since shortly after her first suicide attempt in 1999, said Dolan, who reviewed her medical records after her first trial at the request of Rusty. A month before the murders, her daily dose had increased to 450 milligrams, twice the recommended maximum dose, Dolan said."

In August 2004, Rusty filed for divorce, stating that he and Yates had not lived together as a married couple since the day of the murders. The divorce was granted on March 17, 2005, after which Rusty began dating his second wife, Laura Arnold. They married on March 25, 2006, and had one son. She filed for divorce in 2015.

Although the defense's expert testimony agreed that Yates was psychotic, Texas law requires that, in order to successfully assert the insanity defense, the defendant must prove that he or she could not discern right from wrong at the time of the crime. In March 2002, a jury rejected the insanity defense and found her guilty. Although the prosecution had sought the death penalty, the jury refused that option. The trial court sentenced her to life imprisonment in the Texas Department of Criminal Justice with eligibility for parole in 40 years.

Yates then stopped taking medication, mutilated herself, and read the Bible feverishly. She stopped feeding Mary. She became so incapacitated that she required immediate hospitalization. On April 1, 2001 she came under the care of Dr. Mohammed Saeed. She was treated and released. On May 3, 2001, she degenerated back into a "near catatonic" state and filled the bathtub in the middle of the day; she would later confess to police that she had planned to drown the children that day, but had decided against doing it then. She was hospitalized the next day after a scheduled doctor visit; her psychiatrist determined she was probably suicidal and had filled the tub to drown herself.

At the time of the murders, Yates' family was living in the Houston suburb of Clear Lake City. She continued under Dr. Saeed's care until June 20, 2001, when Rusty left for work, leaving her alone to watch the children against Dr. Saeed's instructions to supervise her around the clock. His mother, Dora Yates, had been scheduled by him to arrive an hour later to take over for her. In the space of that hour, she drowned all five children.

Yates's brother, Brian Kennedy, told Larry King on a broadcast of CNN's Larry King Live that Rusty expressed to him in 2001 while transporting her to Devereux treatment facility that all depressed people needed was a "swift kick in the pants" to get them motivated. Her mother, Jutta Kennedy, expressed shock when she heard of Rusty's plan while at the gathering with them, saying Yates wasn't stable enough to care for the children. She noted that Yates demonstrated she wasn't in her right mind when she nearly choked Mary by trying to feed her solid food.

He added that his wife was too sick to be discharged from her last stay in the hospital in May 2001. He said he noticed the staff lower their heads as if in shame and embarrassment, turning away without saying a word. The hospital had no other choice due to the ten-day psychiatric hospitalization insurance constraints of their provider, Blue Cross Blue Shield, subcontracted by Magellan Health Services.

Yates's first psychiatrist, Dr. Eileen Starbranch, testified that she urged her and Rusty not to have any more children, as it would "guarantee future psychotic depression". They conceived their fifth and final child approximately 7 weeks after her discharge. She stopped taking Haldol in March 2000 and gave birth to her daughter, Mary, on November 30, 2000. She seemed to be coping well until the death of her father on March 12, 2001.

According to authors Suzy Spencer and Suzanne O'Malley, who investigated her story in great detail, it was during a phone call Dr. Saeed made to Rusty during the breaking news of the killings that Saeed first learned that she was not being supervised full-time. Yates's first psychiatrist, Dr. Eileen Starbranch, says she was shocked to disbelief when, during an office visit with the couple, they expressed a desire to discontinue her medications so she could become pregnant again. She warned and counseled them against having more children, and noted in the medical record two days later, "Apparently patient and husband plan to have as many babies as nature will allow! This will surely guarantee future psychotic depression." Nevertheless, Yates became pregnant with her fifth child, Mary, only 7 weeks after being discharged from Dr. Starbranch's care on January 12, 2000.

Following the birth of her fourth child, Luke, Yates became depressed. On June 16, 1999, Rusty found her shaking and chewing her fingers. The next day, she attempted to commit suicide by overdosing on pills. She was admitted to the hospital and prescribed antidepressants. Soon after her release, she begged Rusty to let her die as she held a knife up to her neck. Once again hospitalized, she was given a cocktail of medications including Haldol, an anti-psychotic drug. Her condition improved immediately and she was prescribed it on her release. After that, Rusty moved the family into a small house for the sake of her health. She appeared temporarily stabilized.

In July 1999, Yates suffered a nervous breakdown, which culminated in two suicide attempts and two psychiatric hospitalizations that summer. She was diagnosed with postpartum psychosis.

Yates claimed that, despite his urging to check her medical records for prior treatment, Dr. Saeed had refused to continue her regimen of the antipsychotic Haldol, the treatment that had worked for her during her first breakdown in 1999.

The real question to me is: How could she have been so ill and the medical community not diagnose her, not treat her, and obviously not protect our family from her ... Rusty testified that he never knew that she had visions and voices; he said he never knew she had considered killing the children. Neither did Dr. Saeed, even though the delusions could have been found in medical records from 1999 ... he reluctantly prescribed Haldol, the same drug that worked in a drug cocktail for her in 1999. But after a few weeks, he took her off the drug, citing his concerns about side effects ... though her condition seemed to be worsening two days before the drownings, when Rusty drove her to Dr. Saeed's office, he testified, the doctor refused to try Haldol longer or return her to the hospital.

They announced that they "would seek to have as many babies as nature allowed", and bought a four-bedroom house in Friendswood, Texas. Their first child, Noah, was born in February 1994, just before Rusty accepted a job offer in Florida, so they relocated to a small trailer in Seminole. By the time of the birth of their third child, Paul, they moved back to Houston and purchased a GMC motor home.

Yates 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 she worked as a registered nurse at the University of Texas MD Anderson Cancer Center. In summer 1989 she met Russell "Rusty" Yates at the Sunscape Apartments in Houston. They soon moved in together and were married on April 17, 1993.

She 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.

Andrea Pia Yates (née Kennedy; born July 2, 1964) is a former resident of Houston, Texas, who confessed to drowning her five children in their bathtub on June 20, 2001. She had been suffering for some time from very severe postpartum depression, postpartum psychosis and schizophrenia. During her trial, she was represented by Houston criminal defense attorney George Parnham. Chuck Rosenthal, the district attorney in Harris County, asked for the death penalty in her 2002 trial. Her case placed the M'Naghten rules, along with the irresistible impulse test, a legal test for sanity, under close public scrutiny in the United States. She 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 40 years. The verdict was overturned on appeal, in light of false testimony by one of the expert psychiatric witnesses.
