Trace Evidence

The Trace Evidence Collection Guide is a companion mobile app to the OSAC developed Trace Materials Crime Scene Investigation Guide as a quick reference for crime scene teams and law enforcement officers to use for the recognition, collection, and preservation of trace evidence. The app enables the guide's content to be accessed, searched, and referenced at any time and in any location. With the guide’s information easily accessible, users can view descriptions of different types of trace evidence, information about crime scenes where trace evidence might be encountered, and guidance outlining the collection and packaging of trace evidence.
