The victim was named as Heather Heyer, 32, a legal assistant from Charlottesville.
Heyer, said Wilson, was strongly opposed to President Donald Trump, and she also spoke out against Jason Kessler, the blogger who organized the "Unite the Right" rally that was broken up before it began on Saturday. She stood up against "any type of discrimination", he said.
"Dear @NYCMayor- I am calling on you to immediately fire NYPD Officer Daniel Pantaleo". "I always encouraged her to be strong", her mother, Susan Bro, told NBC News. He said she had a good eye and was a "people person".
A Charlottesville, Virginia rally to keep a Confederate statue and the counter-protest to take it down stunned the country after a vehicle drove into a crowd of counter-protestors, killing Heather Heyer and wounding many others.
Heyer split her time between helping others as a paralegal and protesting in her spare time.
Multiple videos of the crash surfaced after the incident, showing a gray Dodge Charger driving straight into a crowd.
Nineteen were injured in the attack, including Heyer's friend, Marcus Martin.
"I hear tires screech, then I look up and I see people getting thrown in the air and the only thing I could do is push my fiancée out of the way", Martin said.
Amazingly, Marcus survived the hit - but suffered a broken leg. "Hate will not win, love is going to triumph", said Beth Finn.
Bro said she had dinner with her daughter about a week ago. Heather was such a sweet soul, and she did not deserve to die. "I'm proud of her for standing up".
"She died trying to bring about that goal", he told CNN on Sunday, the day after he was told his 32-year-old daughter had been run down on a Charlottesville, Virginia, street. The situation escalated quickly and at approximately 1.45pm a auto, being driven by 20-year-old James Alex Fields Jr., ploughed into a group of protestors.
"I've never had a close friend like this be murdered", Ms. Blair said.
Several non-profits in the Charlottesville area are reporting an uptick in donations in response to the violent white supremacist rally that shook the college town. Federal authorities have opened a civil rights investigation into the attack, saying "such actions arise from racial bigotry and hatred".
