Homicide followed by Suicide

1. Most men who shoot and kill their intimate partners then kill themselves (Kentucky).

We analyzed data from the Kentucky Firearm Injury Statistics Program for 1998-2000.

Major findings:  While less than 7% of all firearm homicides were followed by a firearm suicide, in two-thirds of the cases in which a women was shot in an intimate partner-related homicide, the male perpetrator then killed himself with the firearm.  Few of these female victims had contact with the Department of Community-based Services.

2. Most men who shoot and kill their intimate partners then kill themselves (many states)

We analyzed characteristics of homicides that were followed by suicide and by suicide attempts using data from multiple sites. Fifty-nine percent of the men who killed a female intimate partner with a firearm also took their own life.

3. High rates of homicide followed by suicide in U.S. likely due to firearm access

In a comparison of homicides-suicides in the Netherlands, Switzerland and the United States (using NVDRS data), major differences—e.g., Switzerland and the US have much higher rates of homicide-suicide than the Netherlands—are explainable by the availability of firearms
