Why is there a need to find out why? Killing spree is a lot like thunderbolt. It has no prediction why it struck, in the path it stuck. If you only want to minimize risks of future murders, then don't read/watch the news. Each time a murderer has his/her face shown, she/he is glorified in even tiniest of ways (i.e. comic book villain), with a number of murders he/she committed put in front line, number of violent copycat acts will spike.
