Abstract
|
PURPOSE The study aims to examine the effect of detective experience on the likelihood of clearing a homicide, while controlling for additional extralegal and case/investigative characteristics.
DESIGN/METHODOLOGY/APPROACH This study uses homicide and policing data collected from case files in a mid-sized US city. Detective experience is measured in multiple ways. Analytical models include extralegal variables, case characteristics, and proxies of investigative quality as controls. The study uses logistic regression with a dichotomous clearance outcome.
FINDINGS The results suggest a robust and significant inverse relationship between the years spent as a homicide detective and the likelihood of case closure. However, years of experience with the department overall has a significant and positive relationship to clearance. Investigation-related variables and case characteristics contribute more to model explanatory power than extralegal factors.
ORIGINALITY/VALUE The potential role of experience has not been fully explored, with contradictory findings over time. This work builds on previous research to highlight the potential role of experience in clearing cases, while questioning previous assumptions tied to the belief that more experience improves investigative outcomes.
