If you go back in the threads to when we first got news of the shooting, you'll find all kinds of varying reports. The victim was shot anywhere between 7:59 and 8:45. He was shot in the head. He was shot in the chest. He was shot in the abdomen. And much of this was OFFICIAL sources putting out the info. Even the LEOs didn't agree as to the facts. I guess that is just part of breaking news. Everyone's talking to different sources and getting different "facts".
As to the time of the shooting, I go with the 7:59 since this is the first report. I figure the other times represent the time at which the corresponding LEO agencies, etc. were notified.
They also said, initially, he was shot in the back.
