ALL KINDS OF KILLERS

Your story has a killer.  Your hero must stop him.  But is your villain a serial killer, a spree killer, or a mass murderer?  Or none of the above.  You must know the difference to understand how to characterize your antagonist.

A serial killer has killed multiple times but always at a different location over a period of time. There is usually a pattern as to location, type of victim, method of murder, etc. with the victim almost always previously unknown to the killer.  The Ted Bundys and John Wayne Gacys fit in this category.
