US neo-Nazi in Charlottesville filled with 'anger' prosecutor says

The 21-year-old from Ohio is accused of first degree murder over the killing of Heather Heyer, 32, as well as hit-and-run charges and eight counts of causing serious injury.

Hundreds had descended on Charlottesville on the day of Heyer's death, August 12, 2017, either to march in or rail against a "Unite the Right" rally.

Unrest quickly flared as riot police and National Guard troops flooded the city's downtown to contain clashes between white far-right supporters and counter-protestors that led to a state of emergency being called.

The violence capped two days of confrontation over the removal of a Confederate statue that shook the country, and became a symbol of the growing audacity of the far right under President Donald Trump.

Prosecutor Nina Antony told the jury that a mountain of photographic and video evidence would show Fields' actions were pre-meditated and not motivated by a desire to protect himself, as the defense would argue.

These included two images, she revealed for the first time, that were posted by Fields to Instagram in May 2017.

"And in both those images you'll see a group being struck, described as protesters," she said.

"On August 12, James Alex Fields Jr was here in Charlottesville with anger and images of violence fixed in his mind. The case is about his decision to act on that anger and those images."

- 'Bodies flying everywhere' -

The court heard from witnesses including Marcus Martin, the subject of a Pulitzer-prize winning photograph that became synonymous with the incident, in which he is seen launched into the air after being struck by the car.

Martin told the court he had decided to attend the rally with his fiancee Marissa Blair, whom he has since married, another friend and Heyer, who worked with Blair at a law firm.

"She was a great person," he said of Heyer, visibly overcome with emotion.

Martin recalled looking down at his phone when Fields began his charge on the group.

"The only thing I was thinking about is getting my wife out of the way," he said.

"I pushed her and that's when I got hit." The impact shattered Martin's left leg and broke his ankle, forcing him to wear a medical boot for eight months.

Another witness, Brendan Gilmore, said he had gone with a group of friends to join the counter-protest and began filming on his phone when "I saw bodies flying everywhere."

"I wasn't sure at the time if I pressed record or not. I didn't know until later that I had caught it all on video," he added.

- State of mind -

The lawyer painted a picture of chaos as the opposing sides, some of whom were armed with guns, fought pitched battles.

After Fields was detained, he expressed remorse and told police he "feared for his safety and that he was scared to death," Hill said.

Antony, the prosecutor, disputed that characterization.

Shortly before Fields drove his gray car into the crowd, she said, he came to a "full and complete stop a distance from the group" and began revving his engine while watching the counter-protesters.

"There was no one around the car. There was no one behind the car," Antony told the jury.

While others were able to jump clear or were hit glancingly, Heyer was "directly in the defendant's path, unable to get out of the way.

"The defendant (was) able to get away with her blood and her flesh still on his vehicle."
