A little off topic, but what motive could the drug gangs have to murder these particular people?
From what I have read these students were commie wannabe thugs. They often stole, vandalized, and otherwise harassed businesses. Amongst other things they were in the habbit of commandering public busses, forcing off people trying to get home or work or wherever. I appears the little commies finally stepped on the toes of businesses owned by someone less civilized than the captalists they claim are so oppressive.
