To determine whether recommended robbery prevention strategies also protect against workplace homicide committed by a perpetrator who has a relationship with either the workplace or an employee (prior-relationship homicide).
A case–control study examining the relationship between recommended violence prevention strategies and prior-relationship workplace homicides in North Carolina was conducted.
Workplaces located in an industrial park, employing minorities, reporting a history of violence, open night hours, or open 24 hours were more likely to experience prior-relationship homicide. Keeping entrances to the workplace locked when employees were present (OR = 0.36, 95% CI: 0.13, 0.99) and having at least one security device (OR = 0.28, 95% CI: 0.10, 0.74) decreased the odds of prior-relationship homicide.
Select strategies recommended to prevent robberies and subsequent violence may also afford protection against prior-relationship homicide.
