Homicides Clearances

Abstract

A number of studies in the homicide clearance literature combine arrest and exceptional clearances into a single category. This study addresses the question of whether these divergent homicide case outcomes are influenced differently by various aspects of the case. Using National Incident-Based Reporting System data on homicides from 1996 to 2002, the authors analyze logistic regression models of cases cleared by arrest and exceptionally cleared. Our results show that although certain factors have similar influences on both arrest and exceptional clearances, victim gender, offender race, weapon use, victim/offender relationship, and circumstances have differing impacts on case outcomes. The findings challenge recent research findings on clearances suggesting that exceptional clearances are almost solely politically motivated, and implications for measuring clearance are discussed.
