A murder trial begins in Massachusetts for a woman accused of killing her three children. Multiple outlets report that jury selection is underway and the case concerns the deaths of the children and the defendant’s claim that her actions were linked to psychiatric problems that developed after childbirth. The Washington Times says the prosecution alleges she strangled the three children, while the defense is expected to argue that postpartum issues—described as postpartum psychosis or postpartum mental health problems—played a role in the killings. The Independent characterizes the anticipated defense position as that postpartum issues led her to kill the children. Although details of the medical treatment and the specific diagnosis are not fully set out in the provided excerpts, the reporting is consistent that the defendant has been receiving or has received medical treatment for psychiatric conditions that emerged after giving birth. The trial is expected to address both the circumstances of the killings and the defendant’s mental state in the period surrounding the deaths, with the court process beginning with jury selection.
