Soda Crackers and Insanity

In my English class we had to write a mystery story. In the story there had to be a victim, and a murderer. We picked out of an envelope a few of the components for the story. I will list the things I got.

Characters: video store clerk & championship chess player.
Scene: an oasis.
Weapon: soda crackers.
Motive: hatred.

My story is very lame, in my own opinion. But, I suppose it'll get the job done.

DISCLAIMER: I do not own Robert McCracken, Jepharee Howard, or Zachary Baker.
