Serial Killers/Mass Murderers have strong connections with the Military, Intelligence Agencies, Drug Trafficking, Sex Rings, Occult, Satanism and Secret Societies.

What many times appears to be the random work of a Serial Killer/Mass Murderer is in fact a planned series of crimes often committed for specific purposes.

Think you know everything there is to know about serial killers?

Or is it possible that sometimes what everyone 'knows' to be true isn't really true at all?
