accepted a job offer in Florida, causing them to relocate to a small trailer in Seminole. By the time of the birth of their third child, Paul, they had moved back to Houston and purchased a GMC motor home. Following the birth of her fourth child, Luke, Yates' depression resurfaced. On June 16, 1999, Rusty found her shaking and chewing her fingers. The next day, she attempted suicide by overdosing on pills, leading to her being hospitalized and prescribed antidepressants. Soon after her release, Yates begged Rusty to let her die as she held a knife up to her neck. Once again hospitalized, she was given a plethora of medications, including Haldol, an anti-psychotic drug. Yates' condition improved immediately, and she was prescribed it upon her release. After this incident, Rusty moved the family into a small house for the sake of her health. She appeared temporarily stabilized. In July 1999, Yates had a nervous breakdown, which culminated in two suicide attempts and two psychiatric hospitalizations that summer. She was subsequently diagnosed with postpartum psychosis. 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 seven weeks after her discharge. Yates stopped taking Haldol in March 2000 and gave birth to her daughter, Mary, nine months later. Yates seemed to be coping well until the death of her father on March 12, 2001. She then stopped taking medication, mutilated herself, read the Bible feverishly, and stopped feeding Mary. She became so incapacitated that she required immediate hospitalization. On April 1, 2001, Yates 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. Yates was hospitalized the next day after a scheduled doctor visit; her psychiatrist determined she was probably suicidal and assumed she had filled the tub to drown herself. Murders At the time of the murders, the Yates family was living in the Houston suburb of Clear Lake City. Yates continued under Dr. Saeed's care until June 20, 2001, when Rusty left for work, leaving her alone
