Last time around I established, by thoroughly watching a thoroughly unwatchable film, the identity and motive of the killer in 'Chain Letter'. But in researching that article I came across a mystery that even I couldn't solve. Take a look at this-

That shot appears at the end of the opening credits. A bald man has a chain wrapped around his neck and a gun pushed against head. Who is this man? Why is he being murdered? By whom?
It seems like a complete non-sequitor, except for one thing. This man appears in one other scene. In fact, the chronologically first murder scene in the film!
