Complete the short story / flash fiction, that has the following first paragraph:
The convention floor was crowded, jammed packed with cosplayers and fans, buyers and sellers. He took a deep breath and inhaled old paper, new plastic and warm hot dogs. His stomach growled reminding him that his shift was over in thirty minutes and he could abandon the rent-a-cop outfit he had on and go after some real prey. As he surveyed the crowd one more time a tall figure, dressed like the grim reaper caught his attention. As the figure walked his robes parted and he saw what caught his attention. The grim reaper never used a gun.
