[Inkscape-user] Inkscape and crime scenes

I'm a crime scene investigator and have beeen investigating the use of Inkscape for crime scene sketching. Has anyone else done this? It has all of the features that the high end programs do. I can not find any open source libraries of crime scene symbols to use with it though. I have begun compliing a libray myself. If no one out there has an open source one I will continue. It will have a large number of files and I would like to make it available in one download. The clip art area would not be approaite due to the large number of files. Any suggestions?
