In a Massachusetts courtroom, a former labor and delivery nurse’s mother testified that her daughter told her she had “thoughts of harming the children.” That moment came during the third week of Lindsay Clancy’s trial, where the 36-year-old mother admits she killed her three young children—Cora, Kalen, and Dawson—in January 2023 but claims she was suffering from undiagnosed postpartum psychosis and was over-medicated. Meanwhile, in Manhattan, Luigi Mangione stunned a federal courtroom by pleading guilty to stalking charges in connection with the December 2024 shooting of UnitedHealthcare CEO Brian Thompson, then immediately filed a motion to dismiss parallel state charges on double jeopardy grounds.
