Intimate partner homicides spiked by 22% in the five years from 2018 to 2022, according to a report released Thursday by Brady: United Against Gun Violence, a gun reform advocacy group.

An American now fatally shoots their spouse or dating partner every 12 hours, the groups analysis found. That rising violence, overwhelmingly directed at women, most commonly occurs in states where access to firearms is easiest.

The report, based on data collected by the Gun Violence Archive , comes as the Supreme Court prepares to hear a closely watched case that will decide whether people subject to protective orders for domestic violence can retain their gun rights.
