Abstract

Approximately one in seven homicides globally is committed by a partner within an intimate relationship. While criminology research on intimate partner homicide (IPH) perpetrators is extensive, their interactions with law enforcement remain underexplored. This study examines the criminal trajectories of IPH perpetrators to ascertain whether they exhibit common or diverse patterns. Utilizing data from Quebec’s official criminal events database, the study analyzes variables concerning the criminal histories of 1,780 individuals involved in attempted or completed IPH through latent profile analysis. Findings indicate five distinct profiles among IPH perpetrators: one-time, low-volume intimate partner violence (IPV), moderate-volume IPV, high-volume violence, and high-volume polymorphous perpetrators. The external validity of these profiles is assessed using additional criminal career, contextual, and situational variables. Implications for the justice system’s practices and challenges are also discussed.
