DOWNINGTOWN, Pa. – July 15, 2013 (WPVI) —┬áPolice in Chester County, Pennsylvania are investigating an act of vandalism with racial overtones, possibly connected to the fallout from the verdict in the George Zimmerman murder trial.

Photographs obtained by Action News show what firefighters found Sunday night when they responded to a fire at ProSigns, a company that manufactures commercial signs for businesses, in the 200 block of Boot Road.

You can clearly see the words “Kill Zimmerman” painted in red paint on the front wall.

The graffiti was discovered when firefighters arrived to extinguish a blaze around 11:20 p.m. Sunday.

The fire was brought under control quickly and no one was hurt. Considering the graffiti, investigators immediately suspected the blaze was intentionally set.

On Monday, the fire was ruled an arson, fueled by an unknown accelerant.
