The study assesses the extent to which gun assaults are clustered in space and time using crime data from Houston, Texas. The analysis examines patterns of gun assaults at the city-level as well as more localized levels in order to understand the spatial distribution of near-repeats within the city. Consistent with prior research, the city-level analysis shows significant and meaningful near-repeat patterns. The localized analysis indicates that the risk of near-repeats is not evenly distributed across space within the city, but is concentrated among a small portion of incidents and four relatively small spatial clusters. In addition, an examination of crime types, locations, and gang involvement shows slight differences between gun assaults with and without near-repeat follow-up shootings.
