Sexual Homicide in France.

The primary objective of this study was to describe and compare the modus operandi, and associated contextual and situational factors, of French serial sexual murderers (SSMs) and nonserial sexual murderers (NSMs). A further objective was to verify the generalizability of the conclusions of James and Proulx's 2016 systematic review of the modus operandi of sexual murderers, the majority of whom were American or English. Detailed data on the precrime, modus operandi, postcrime, and victimology factors of 120 French sexual murderers (SSMs: = 33; NSMs: = 87) were compared.
