Intimate partner violence (IPV) is prevalent but underrecognized; at least 25% of United States women experience IPV within their lifetime. We examined the most severe consequence of IPV by exploring the patterns of death from IPV in a statewide database of homicide victims.This is a retrospective review of the Colorado Violent Death Reporting System from 2004 to 2015. Deaths were coded as IPV if the primary relationship between the suspect and victim fell into the following categories: spouse, ex-spouse, girlfriend/boyfriend, and ex-girlfriend/ex-boyfriend.We identified a total of 2279 homicide victims, with 295 cases of IPV homicide (12.9%). The majority was female victims of a male partner (n = 240, 81.4%). In nearly half of these (n = 108, 45%), the male suspect subsequently died by suicide as part of the same incident. These homicide-suicide incidents were more likely than homicide alone to involve a spousal relationship, more likely to involve firearms and less likely to involve intoxication or preceding arguments. They had a distinct demographic profile from other victims of IPV, mirroring suicide victims in terms of race and estimated income.These results indicate that there are two distinct groups of female IPV homicides, and recognizing this distinction may allow for the development of more effective trauma prevention strategies. Homicide-suicides showed a more premeditated pattern while homicide alone suggested a crime of passion, with a smaller proportion of firearm deaths and higher rates of positive toxicology findings and preceding conflict in the latter group.
