RICHMOND, Va. (AP) — Friends and family are mourning the death of a protester and two Virginia state troopers who died Saturday in Charlottesville, where a car plowed into a group of people protesting a white nationalist rally and a police helicopter crashed.

Heather Heyer, who was protesting against white supremacists, was killed after a car rammed into a crowd of protestors. Friends describe her as a caring person who fought for causes she believed in.

Troopers Lt. Lt. H. Jay Cullen and Trooper-Pilot Berke M. M. Bates died after their helicopter crashed into a wooded area just outside the city. They had been part of a large-scale police effort at the rally. Friends and family said both men loved their jobs.

The driver, James Alex Fields Jr., a 20-year-old who recently moved to Ohio from where he grew up in Kentucky, was charged with second-degree murder and other counts.

He’s due in court on Monday.
