The mother of a slain and dismembered 14-year-old Pennsylvania girl has testified that she told her daughter she had no interest in helping her as she was being attacked. When her daughter Grace looked at her for help as Jacob Sullivan punched her in the face, Sara Packer said she told her, “I can’t help you anymore. This is your life now.” Sara Packer said she wanted her daughter dead. She testified Wednesday at a sentencing hearing near Philadelphia for Sullivan, her boyfriend.
