Opening statements to begin in trial of Lindsay Clancy, mother accused of killing 3 children

Key Points:

• Lindsay Clancy, a Massachusetts mother, is on trial for the triple murder of her three children, with opening statements beginning Monday; she has pleaded not guilty, claiming postpartum psychosis and severe mental illness as her defense.
• Clancy fatally strangled her children in January 2023 and then attempted suicide, leaving her partially paralyzed; prosecutors argue deliberate premeditation, while her defense cites extreme mental illness affecting her culpability.
• The trial will focus heavily on psychiatric testimony regarding postpartum mental illness, with Clancy's husband as a key witness supporting her mental health struggles.
• Clancy's lawsuit against her medical providers alleges misdiagnosis and improper treatment of her postpartum bipolar disorder, which she claims contributed to the tragedy.
• The case echoes high-profile insanity defense trials like Andrea Yates and John Hinckley Jr., highlighting the rarity and complexity of such defenses in criminal cases.
