In March 2014, Carol Coronado was a new mother who committed an unthinkable act of violence: She stabbed and killed her three daughters, who were all under the age of three. Coronado's lawyer unsuccessfully argued that she was in the grip of an acute mental illness when she attacked her children. The judge said he thought Coronado was suffering from a mental condition and then sentenced her to three consecutive life terms without parole. In this week’s episode of the Mother Jones Podcast, host Jamilah King is joined by KQED health reporter April Dembosky to talk about her yearlong investigation into a devastating but under-reported condition called postpartum psychosis. The condition afflicts one to two moms out of 1,000 births, but psychiatrists believe that could underestimate the frequency because the symptoms are so easy to miss. Dembosky constructs and analyzes the data behind postpartum psychosis and looks into how the health care and legal systems could better serve women affected by this frightening condition. This radio documentary was first aired on KQED's California Sunday Magazine show earlier this month.
