(NEWSER) – An 8-year-old boy fatally shot his elderly "caregiver"—WBRZ identifies the victim as his grandmother—in Slaughter, Louisiana, last week, authorities say. The victim was Marie Smothers, 87. The boy has not been identified because of his age. He originally told police the shooting was unintentional, but authorities say their investigation has led them to believe the boy "intentionally shot Mrs. Smothers in the back of the head as she sat in her living room watching television," CNN reports. The gun belonged to Smothers, reports WBRZ.
