Summary: A study that utilizes 10 years of data on intimate partner homicide reveals men who have a history of domestic violence and access to guns have an increased risk of committing murder-suicide. Restricting gun access to men with a history of domestic battery could reduce murder suicide rates, researchers report.
Men who use guns to kill their partner are also likely to commit suicide. Those planning to commit suicide are not deterred by severe penalties, and therefore the most successful way of preventing such homicides is to restrict gun access to batterers. So says Sierra Smucker of Duke University Sanford School of Public Policy in the US. She is the lead author of a study in Springer’s Journal of Urban Health. The research also shows that in cases where a man has killed his partner using a gun there are more likely to be multiple homicide victims than when no gun is involved.
Smucker and her colleagues analyzed data extracted from the North Carolina Violent Death Reporting System between 2004 to 2013. As the state-wide system links all violent deaths occurring in the same incident, Smucker’s team was able to extract information from all incidents that included both a suicide and a murder.
During the decade under investigation, 6,440 homicides were reported in North Carolina. Of these, 813 (16.8 per cent) cases involved murder of a person by someone identified as their intimate partner. Women were the victim in three out of every four such cases, and were killed 99 per cent of the time by a man.
Furthermore, the researchers found that one in every two cases in which someone was murdered by their intimate partner also ended in the perpetrator committing suicide. Guns were the weapon of choice seven out of every ten times. In 86.6 per cent of these cases, men pulled the trigger before turning the gun on themselves too. Men were also more likely to kill other victims including the victim’s children or parents if a gun was used. Including these additional deaths, male-perpetrated incidents of intimate partner homicide averaged 50 per cent more deaths if a gun was used compared to similar crimes committed with other weapons.
The findings support previous research that suggests homicide-suicides are more prevalent in intimate partner homicides than other types of murders, and that firearms are often the weapon of choice for such crimes. Existing research and this study show that children and other family members are often also victims in such crimes.
“It is well known that gun access increases the chance that a violent domestic relationship will end in death,” says Smucker. “The current findings demonstrate that intimate partner homicides through the use of guns are often coupled with additional killings.”
She says the conclusions underscore the importance of firearm restrictions, and the need to broaden the definition of domestic violence. She believes that all federal and state laws should include people who abuse their partners regardless of whether they are married to them or not. This is because the current study found that intimate partner homicides involving unwed partners are more likely to include additional victims than is the case with ones involving married couples.
“It is important to pre-empt gun access by suicidal batterers, rather than depending on the deterrent effect of the threat of severe penalties or punishment,” maintains Smucker. “Someone who plans to commit suicide is logically beyond the reach of the legal threat.”

Suicide and Additional Homicides Associated with Intimate Partner Homicide: North Carolina 2004–2013
Intimate partner homicide (IPH) is a critical public health and safety issue in the USA. In this study, we determine the prevalence and correlates of perpetrator suicide and additional homicides following intimate partner homicide (IPH) in a large, diverse state with high quality data. We extract IPHs from the North Carolina Violent Death Reporting System for 2004–2013 and identify suicides and other homicides that were part of the same incidents. We analyze the likelihood (in odds ration form) of perpetrator suicide and additional homicides using logistic regression analysis. Almost all IPH-suicide cases were by men with guns (86.6%). Almost one-half of IPHs committed by men with guns ended with suicide. Male-perpetrated IPH incidents averaged 1.58 deaths if a gun was used, and 1.14 deaths otherwise. It is well-known that gun access increases the chance that a violent domestic relationship will end in death. The current findings demonstrate that gun IPH is often coupled with additional killings. As suicidal batterers will not be deterred from IPH by threat of punishment, the results underline the importance of preemption by limiting batterers’ access to guns.
