Mother's postpartum psychosis led to horrific tragedy.

A mother stands accused of three counts of first-degree murder following the January 2023 deaths of her three children. Prosecutors allege she strangled the children with fitness bands in their Massachusetts home before attempting to end her own life by jumping from a second-story window, an act which left her paralyzed.

Testimony from a forensic psychiatrist indicated that the defendant lacked control and moral understanding during the incident. He testified that she likely believed she was sparing her children by taking them with her to heaven. The defense has presented evidence of hallucinations and delusions, stating the mother was undergoing psychiatric treatment and had briefly checked herself into a hospital prior to the deaths.

Clancy's mother and former mother-in-law have also testified about her deteriorating mental health after the birth of her youngest son, describing her as a loving mother who was begging for help. The case is nearing its conclusion, with the jury expected to deliberate early next week after nearly a month of witness testimony.
