I typed up rap sheets and made evidence bags (complete with detailed tags). I used masking tape on the floor to create the "chalk" outlines of the bodies. I used random fake body parts to create the scene - a band of misfits with a taste for hacking up victims broke into the office and killed everyone. I used my Polaroid camera as a prop and also took some crime scene photos with it.
Here's my mugshot...I look like Where's Waldo!
And here's my favorite alter-ego name that I came up with... M. Urder-Schtop!
