Police found the body of 16-year-old Calyx on her bed under a white blanket. They found her 13-year-old brother Beau in the family car covered up the same way. Both had two gunshots to the head. Both had been dead for hours. The only other person who had been in the home was their mother, Julie Schenecker. She told law enforcement that she could no longer tolerate her kids talking back to her. Was this a case of premeditated murder? Or a horrible tragedy fueled by a mental illness that had spun out of control? Sleep My Darlings is the deadly true story of a mother's betrayal of her natural instincts and the loss of two innocents' lives.
