Ye olde second suspect has dropped clean away from discussion.
“second suspect”
That could have just been an erroneous report that made its way into the story early. Often those errors are simply dropped from the story line with no explanation.
Or, it could be that the kid was a well intentioned CC holder shooting at the real murderer (2nd suspect) who was actually an FBI agent. The cops see the kid first and take him out. Laughing at his good fortune, the FBI guy makes his escape.
Seems to happen. A lot.
I live across the street from this event and have doubts about second shooter.
This place crawls with uniform LEO inside and outside.
And there is an extended perimeter.
There isn’t a way to escape detection.
There are even police and sheriff Explorers controlling areas surrounding
He would have been seen
There were conflicting descriptions of the shooter and I suspect the 2nd man is erroneous
