Four billboards have appeared in Wichita, Kansas; all of them bearing the same somber message: “Andy Finch is dead. If you believe in justice, it’s time to file charges.”

In December, a Wichita police officer fatally shot Andy Finch after a fake emergency call directed law enforcement to the 28-year-old victim’s home. A man in California has since been charged with involuntary manslaughter for the so-called “swatting” hoax call, but the  family of the man who was killed and community activists have repeatedly called for the officer who killed Finch to come under greater scrutiny.

The billboard campaign seems to be inspired by the film “Three Billboards Outside Ebbing, Missouri,” which revolves around a distraught mother’s crusade for justice following the murder of her daughter.

Like the billboards in the film, the ones in Wichita featured bold black letters on a plain red background, Yahoo reports.
