If all witness statements were consistent, I'd say yes, but they aren't so it comes down to the forensics will tell the story. Voice analysis, shot trajectory, location of the body, where his cell phone ended up. This "John" was so in a hurry to get into the house, lock his back door and ran to the second floor, I believe, while calling 911. By that time it was too late. I doubt he stopped more than a second to look as it appears, by his own admission, he made a beeline to his back door. If the voice analysis is correct that it wasn't GZ's voice it shoots John's statement right out the door. jmo
