Firearms and protective orders in intimate partner homicides.

PURPOSE: To determine differences among intimate partner homicides (IPH) by whether or not a firearm was used in and whether a protective order (PO) was filed prior to IPH. METHOD: We identified all incidents of IPH recorded in the National Violent Death Reporting System from 2003-2018, based on the relationship between victim and perpetrator. We characterized incidents, perpetrators and victims in IPH cases by whether or not a firearm was used, and whether a PO had been sought or issued prior to the IPH. RESULTS: We identified 8,375 IPH incidents with a total of 9,130 victims. Overall 306 (3.3%) victims were killed in a firearm IPH with PO, 4,519 (53.9%) in a firearm IPH without PO, 176 (2.1%) in a non-firearm IPH with PO and 3,416 (40.7%) in a non-firearm IPH without PO. Based on review of incident narratives, 5.4% (n=451) of incidents involved a previously-granted or sought PO, and none of which had explicitly mentioned firearm removal as a part of the PO. CONCLUSIONS: The majority of victims were killed with a firearm. Prior literature suggests that POs with firearm removal may be effective strategies for reducing risk of IPH, but we found no documentation in the narratives that firearm removal was a condition in the POs identified. As very few IPH narratives included documentation of a PO, it is likely that ascertainment of PO status is incomplete and could be an area for improvement in NVDRS data collection efforts
