Sorry. I must admit now that I had it all wrong...
After an extensive review of the video messages the killer left, the only real conclusion one can draw is that he was a complete loon.
There was no hidden commie agenda.
I am sorry to any commies out there who may have been offended by my initial analysis.
Yes he hated rich kids...But that was not why he did the killing...He did the killing because he was a complete crack-pot.
