@oralloy,
Wrong. Trayvokn was standing there, talking normally tok his friend okn his plhone. Sokmeone breathing heavily, as from running, came up to him. By simple process of elimination, that had to be Zim.
z: what are you doing here?
'T: why are you chasing me?
T: get off, get off.
Z grabbed T, Z started it, Z escalated it,Z pulled his gun, T already in fear for his life from the crazy man in self defense apparently tried to get it away, Z at close range then murdered him.
