The adult shooter in this case is going to have a hard time proving self defense if it's true that he left the scene, retrieved the gun, then returned to shoot 3 people. Even if he had pulled the gun while the fight was in progress, he'd have to rely on a disparity of force argument. That didn't work so well for Zimmerman, among others. But leaving the scene to retrieve the gun pretty much kills any self-defense argument, I believe.

It will be interesting to see how this plays out.
