The package is designed to support crime analysts with a statistical toolbox containing a set of alternative instruments for converting spatial data into spatial information. STAC consists of a Time Analyzer and the STAC/Space module, which analyzes the distribution of events on a map. STAC/Space includes automatic searches for two kinds of hot spot areas, nearest neighbor analysis, mean center, and radial searches for events around a specific location. This newsletter contains short articles on the Baltimore County Police Department's use of STAC to fight Halloween-related incidents, auto thefts, robberies, and drug markets; a spatial seminar to be held in August 1993; and the development in Chicago of the Automated Early Warning System for Street Gang Violence Crisis Areas.
