Researching for days upon days I was fixated on the question of how can any two people carry out what they had done? Wanting the facts I turned to any credible source and found many documentations on this event. I believe that people have the right to know what happened step by step because the truth is, knowledge is such a great gift and it is true this world is not a fairytale.

A complete video documentary from the Discovery channel which I hold to be very credible when receiving facts can be found below. I must warn you this video is disturbing and it is filled with actual and reconstructed events. (Warning for mature audiences)

The videos above show in great detail of the events leading up to the attack but the question remains why or how could anyone plan a mass murder and suicide attack for an entire year? Experts have analyzed both killers and came to this conclusion why they pulled it off.
