History

Historical Context

In June 2001 Andrea Yates drowned her five children, leading to a 2002 Dallas County trial where psychiatrist Michael Welner described postpartum psychosis and Judge Sharon Keller guided a 12-member jury through ten hours of deliberation. The conviction was overturned in 2005 after Dr. Park Dietz’s false testimony, and a 2006 retrial found her not guilty by reason of insanity, prompting Texas to revise jury-instruction rules on psychiatric defenses.
