The fire was set to a large sign on the back of Denver resident John Case’s Hentzel Park home. Flames quickly spread to brush behind the property. An officer noticed the fire while on another call and rushed to douse the flames with a hose. Fire crews arrived a few minutes later and extinguished the fire.

“We felt like it was a message to us because whoever did had to know we were home,” Case said.

The 2016 campaign has been an ugly affair even at the most local levels. Campaign field offices have become frequent targets for hate. In Ohio a Trump supporter was arrested after dumping a truckload of manure outside Democratic headquarters in Warren County. No arrests were ever made after a Republican field office in Orange County, North Carolina.

“It’s disappointing … every citizen has a right to express their views without retaliation,” Case said.

Case said he will not try to replace his incinerated sign. With just a week left in the campaign he says it’s too risky for his neighborhood.

“Out of respect for our neighbors I don’t want to invite someone to threaten our neighbors with a fire.”
