The development of sensors capable of obtaining 3D scans of crime scenes is revolutionizing the ways in which crime scenes can be analyzed and at the same time is driving the need for the development of sophisticated tools to represent and store this data. Here we describe the design of a multimedia database suitable for representing and reasoning about crime scene data. The representation is grounded in the physical environment that makes up the crime scene and provides mechanisms for representing both traditional (forms-based) data as well as audiovisual (3D scan and other complex spatial data). Some initial results obtained with tools designed to seed the dataset are reported as well as some components of the final database system.
