evidence: Racial and ethnic disparities among homicide victims, suicide decedents, and homicide-suicide perpetrators are well established in the extant literature. In his seminal study on violence in Philadelphia, Wolfgang (1958, p. 31) [14] cited the overrepresentation of persons of color among homicide victims as "an incontrovertible fact." These racial and ethnic disparities in homicide victimization have persisted through the crime rate drop in the 1990s [15], the September 11th terrorist attack and its aftermath in the 2000s [16, 17], and the emergence of the Black Lives Matter movement and the push toward criminal justice reform in the 2010s [18]. The most recent statistics indicate that homicide rates are almost ten, four, and two times higher among non-Hispanic African American, non-Hispanic American Indian and Alaska Native, and Hispanic persons, respectively, than among their White counterparts [1]. [...] Homicide-suicide tends to be a predominantly White phenomenon. Research has indicated that White homicide offenders are at least two times more likely than non-White homicide offenders to commit suicide [17, 19, 20]. Additionally, persons who die by suicide following homicide are more likely than homicide offenders, but less likely than persons who die by suicide, to be White [21]. [...] S2 Table.
