Andrea Yates, a Texas mother of five, drowned her children in a bathtub on June 20, 2001, shocking the nation. She immediately confessed to police and was later found not guilty by reason of insanity. Her medical history showed years of severe postpartum depression and psychosis, multiple hospitalizations, and suicide attempts. Doctors had warned her husband, Rusty Yates, that further pregnancies could worsen her condition and that she should not be left alone with the children. These warnings went unheeded. Rusty and Andrea adhered to a strict conservative Christian framework that emphasized traditional gender roles, homeschooling, and isolation from secular influences. Andrea gave up her nursing career to become a full-time mother, homeschooling all five children while managing household duties under increasing mental strain. A significant influence was evangelical street preacher Michael Woroniecki, whose writings and sermons the Yateses followed closely. Woroniecki preached that women must be submissive and that modern society was spiritually corrupt. He taught that mothers could lead their children to damnation by failing to follow God’s will. Andrea, in her delusional state, internalized these messages and believed her children were spiritually doomed. This religious pressure, combined with extreme isolation and untreated psychosis, shaped Andrea’s belief that killing her children was a way to save them from eternal suffering. Her statements after the killings reflected this belief, as she said she was trying to be a good mother and protect her children from Satan. Her case remains one of the most deeply tragic examples of how rigid religious ideology and untreated mental illness can collide. Sources: Texas v.
