History

Historical Context

In 2001, Andrea Yates (born 1964) drowned her five children in Houston, Texas, prompting a national debate over postpartum psychosis as a legal defense. The case set a precedent that prosecutors in later cases, such as the 2023 Massachusetts trial of Lindsay Clancy, cite to argue criminal intent. Courts now scrutinize mental-health defenses more closely.
