Sometimes Alfred Wilson still has to take a moment to collect himself after he pulls open files at the law firm where he works and sees Heather Heyer’s handwriting. “I get choked up and have to gather myself before I talk to the client,” said Wilson, who hired Heyer, the 32-year-old paralegal killed nearly a year ago in a car attack during a violent white nationalist rally in Charlottesville, Virginia. The rally that left Heyer dead and dozens more injured proved to be a watershed moment, both for the racist, fringe “alt-right” movement, and for the city itself.
