Emergency response systems can be improved by investigating the motives and manner in which people share information during an active shooter crisis. This article analyzed survey data collected from undergraduate participants at The University of Texas at Austin who were enrolled during the fall of 2010 when an active shooter event occurred on campus. Our findings indicated that distance from a threat predicts an individual's perception of message credibility. Additional findings suggested innovativeness is a strong driving factor in individuals' reliance on social and personal media to contact others who need safety updates. Finally, perceptions of mortality and experience to negative media portrayals were positively related to active information sharing during this event. Limitations and suggestions for future research are offered.
