Understanding the data gathered thus far in a criminal investigation is of great importance, particularly in terms of guiding its future course. One established method of comprehending such data is to incrementally visualize it as a network to ascertain if, and how, objects of interest are connected. In this paper we describe this form of visual data analysis, discuss why current database support for the method is inadequate, present an experimental database query system for exploring data in this manner, and outline areas of future research and development.
