The point is, why didn't you tell him about the deceased, just give him his name and say this guy from kwaMashu is supplying.  What you've just told us about a weapon from kwaMashu, this must be your source.  You can easily catch him now, you've got a weapon from kwaMashu, here's the man, this is your man?  Instead you go and kill him, why?
