The Death of Hunter Grissom

Tracy didn't tell the 911 operator Hunter was coming toward her and she never says it to investigators hours later. He never made a single motion towards her, never raised his hand, any of that. The only motion he was making was getting away from her. I don't see how he could hit her at twelve feet. If Tracy was trying to get a photograph of the Grissom construction sign, why would she pull behind it? Shortly after Hunter was shot to death, the sheriff's department came to Melanie Garner's office to inform her in person. "I immediately started to say, I said the bitch did it, the bitch didit, the bitch Did It"
