he was actually killed by the tragedy of gun violence
So you are saying he regained consciousness, learned about the gun violence and the magnitude of that killed him. Sure. I could see it.
Looks like this occurred in a gun-frèe zone
Which makes me wonder why gun violence was there
No he was killed by the person who used a gun to murder him.
If he had used any other weapon to kill him the results would have been the same.
The term gun violent is just used tp promote gun control.
I always carry a “violent” gun in case another “violent” gun shows up.
