I heard a little bit about this story but no details. All I can say is "What the fuck!?"
There's so much wrong with this situation that it's crazy! The kid was 8-years old, with a 90 year old woman, and he had a gun!? The kid was probably watching the 90 year old! Also, was the kid tested for drugs? I wouldn't be surprised to discover that he was high on PCP and had just finished watching bukakke porn.
