Non-fatal strangulation (NFS) is a form of intimate partner violence (IPV) and a strong predictor of intimate partner homicide (IPH). We compile NFS statute data, link them to homicide reports, 1990–2019, and estimate effects on IPH using a two-stage difference-in-differences estimator for staggered adoption and heterogeneous effects. NFS laws reduce IPH for ages 18–49, by 0.169 female-victim homicides per 100,000 women and 0.090 male-victim homicides per 100,000 men. We find no effects on IPH for ages 50–70 or on stranger-perpetrated homicides. Evidence from reported IPV incidents is suggestive of changes in reported incident classification and arrest patterns.
