An Ohio man accused of plowing a car into a crowd of activists in Charlottesville, Virginia, on Saturday, killing one person and injuring 19, was denied bail Monday in his first court appearance.

James Alex Fields Jr., 20, appeared via a video link from Albemarle-Charlottesville Regional Jail and was held on multiple felonies in the incident that occurred during a white nationalist rally that saw clashes between protestors and counterprotestors.

Prosecutors did not detail the evidence against the Maumee, Ohio, man who came to Virginia to attend the rally, according to his mother who spoke over the weekend.

Fields is charged with one count of murder, three counts of malicious wounding and one count of hit-and-run.

The Justice Department also has launched a civil rights investigation into the car ramming, and on Monday U.S. Attorney General Jeff Sessions said in television appearances that the violence in Charlottesville met the definition of domestic terrorism.

Fields replied “no sir,”when asked in court whether he has any ties to the Charlottesville community.

A former teacher of Fields has said that Fields espoused extremist ideals at least since high school. Derek Weimer, a history teacher, said in a weekend interview that he taught Fields in his junior and senior high school years in Kentucky.

Heather Heyer, 32, of Charlottesville was killed Saturday when police said that Fields barreled toward her and other counterprotestors in his Dodge Challenger as he drove “at a high rate of speed” rear-ended another car and pushed vehicles into a crowd of pedestrians. Police charge that Fields then backed up and fled.

In a separate incident, two Virginia state troopers monitoring the protest were killed when their helicopter crashed in woods not far from Charlottesville.

In a written statement, Charlottesville’s Commonwealth Attorney Dave Chapman said the community “is deeply saddened by the loss of Ms. Heyer and by the injuries that were sustained by many people who, like her, were doing no more than peacefully expressing their strongly held beliefs.”

Chapman said final decisions on charges against Fields would be made after the Charlottesville Police Department completes its ongoing investigation.

At his appearance before Judge Robert H. Downer Jr. in Charlottesville General District Court, Fields said he could not afford an attorney and was appointed one by the court.

The weekend rally drew international attention to the city that is home to Virginia’s flagship University of Virginia.

But in a signal of how small a community Charlottesville is, the judge informed Fields that he could not be defended by the Charlottesville Public Defender’s Office because a relative of someone who works for the office had been involved in Saturday’s incident, without specifying if that meant the protests or the crash.

“I’m going to make a decision that you could not have a bond until you see your attorney,” the judge said in appointing Charles Weber to represent Fields.

He set 11 a.m. Aug. 25 as the next court date to consider scheduling of a preliminary hearing.

The judge asked Fields if understood everything that had taken place, and he responded “yes, sir.”

The city’s decision this year to change the name of Lee Park to Emancipation Park and to order the removal of the Robert E. Lee statue from the park has made it a lightning rod for white nationalists and extremists who see it as an attempt to erase white history.
