WATCH: Drone captures clear account of Charlottesville car-ramming incident

One woman was killed and 19 others were injured when 20-year-old James Alex Fields allegedly plowed his car into protesters at a white nationalist rally on Saturday, and new footage shows an overhead angle of the incident.

The bail hearing for Fields, arrested on suspicion of murder, malicious wounding and hit-and-run charges, was set to unfold in Charlottesville as the U.S. Justice Department pressed its own federal hate-crime investigation of the incident.

Authorities said Heather Heyer, 32, was killed when Fields' car slammed into a crowd of anti-racism activists confronting neo-Nazis and Ku Klux Klan (KKK) sympathizers, capping a day of bloody street brawls between the two sides in the Virginia college town on Saturday.

On Friday night, many protesters angered members of the University of Virginia community when they unexpectedly marched on the school grounds chanting messages like "you will not replace us" and "blood and soil" -- a common Nazi-era rallying cry.
