Beginning in November 2012, New Haven, Connecticut, served as the pilot site for Project Longevity, a statewide focused deterrence gun violence reduction strategy. The intervention brings law enforcement, social services, and community members together to meet with members of violent street groups at program call-ins. Using autoregressive integrated moving average models and controlling for the possibility of a non-New Haven–specific decline in gun violence, a decrease in group offending patterns, and the limitations of police-defined group member involved (GMI) categorization of shootings and homicides, the results of our analysis show that Longevity is associated with a reduction of almost five GMI incidents per month. These findings bolster research confirming the efficacy of focused deterrence approaches to reducing gun violence.
