CHARLOTTESVILLE, Virginia — Authorities have identified a suspect who rammed a crowd of protesters during a white supremacist rally Saturday in Charlottesville, Virginia.

According to The Daily Progress newspaper, James Alex Fields Jr., 20, of Maumee in Lucas County, has been charged with second-degree murder, three counts of malicious wounding, and failing to stop at the scene of an accident that resulted in a death after a car plowed into a crowd on the Downtown Mall in Charlottesville. A 32-year-old woman was killed and 19 others were injured in the crash that occurred Saturday afternoon.

Fields is in custody at the Albemarle-Charlottesville Regional Jail.

Two Virginia State Police troopers died in a helicopter crash on Saturday near Charlottesville. They have been identified as H. Jay Cullen of Midlothian, Virginia, and Berke M.M. Bates of Quinton, Virginia, according to The Daily Progress. Bates would’ve have turned 41 on Sunday.
