Clancy’s mental health is a key issue. Her defense has argued she was experiencing postpartum psychosis and was compelled to act by a hallucinated voice when she strangled her children.The prosecution’s final witness, Dr. Gregory Saathoff, a forensic psychologist, testified yesterday that Clancy had the “capacity to appreciate right from wrong” at the time of the killings.After closing arguments, jurors will deliberate over charges of first-degree murder — involving "deliberate premeditation and extreme atrocity" —with the option to consider lesser manslaughter charges.The five-week trial has taken over podcasts, social media and conversations beyond the Massachusetts courtroom. Clancy, 36, has also emerged as a symbol of the gaps in maternal healthcare.
