Although cleared at a higher rate than that of other violent crimes likely because of the resources channeled into such investigations (Federal Bureau of Investigation, 2007) homicide remains poorly understood, and stranger homicides in particular can be challenging for investigators (Dauvergne & Li, 2006). In 2006, the United States experienced an estimated 17,034 homicides, only 60% of which were cleared by police investigation and, most typically, the arrest of at least one person (Federal Bureau of Investigation, 2007).
