It's a hysterical poster.
It could truly be a relative of the dead guy.
No need for moderator, IMO.
Could be. . .but as you know. . .anyone can claim to be anyone and who's to know.
And guess what; I choose to think that poster is not a relative or related in anyway to the dummy that got himself shot.
Fact is; the troll is a ranting lunatic and should not to be tolerated, relative or not.
