Prosecutors have charged a New Jersey woman with murder after she allegedly stabbed her 5-month-old baby daughter to death. CBS Philadelphia reports that police responding to a 911 call from the home of 26-year-old Kristhie Alcazar found the mother of two arguing with someone else while the baby’s body was nearby. Investigators found multiple knives at the scene. A neighbor said they were shocked by the violence because Alcazar “seemed like such a good mom.”
