It’s possible the officer was aiming center mass and fired just after the kid did. That could leave the kid falling at the instant the SRO fired.Interesting conclusion. For that scenario to happen then the 9mm round fired from the shooter had to go through the victims skull, ( yes, she was hit in the head), then down and into the boys leg. Possible, yes , but probable? Secondly, witnesses stated the shooter had the gun pointed at hus head when the officer shot. Aren't they trained to shoot center mass? To hit his gun he must have been attempting a head shot. Not a very high percentage shot under the conditions.
Just a guess, but I agree with you that it’s doubtful he was trying a trick shot to save the kid.
The kid fired two shots. One in each ‘incident’. The first incident was the shot that hit the girl and the 14yo make and 5he second incident involved the suicide shotSounds like the perp fired the magic bullit (like the one that struck both Kennedy and Connolly). And I'm a little confused, if the perp only fired ONE round that struck both victims and the officers shot hit the perps pistol then what bullet killed the perp? Perp must have fired TWO rounds.
