Yes other witnesses told McConnell what happened. That’s what he said in the video anyway.
McConnell saw LaVoy take off - saw the wheels spinning when LaVoy jumped out.
McConnell stated, not hinted, that he did NOT witness the shooting. Anything he has to say on it is hearsay. There are witnesses. One says he had his hands up when he was shot and then shot three more times when he hit the ground. I don’t know if that witness is reliable or not but if her story is corroborated by anybody else some bad juju went down. I will wait on that.
