This documents provides the guidelines for investigators submitting firearm evidence in Indianapolis-Marion County. It has guidelines for every step of the evidence-collecting process. For example, photos that are taken must have a scale (such as a ruler next to it) to show size. In the firearm itself, the investigator is asked to include certain information in their notes such as the appearance of the cylinder, the marks made on each side of the top strap, and diagrams showing the direction of the rotation. There are also directions on how to package cartridges (both fired and unfired) such as making sure they are surrounded by cotton or a similar soft material, that the package is sealed tightly and that the correct information is included on the label. Most of the guidelines are very specific. But there are also some more obvious guidelines, such as that the firearm should be given to the lab unloaded and that weapons should be handled with care.
