The three deaths came on a day in which USA white supremacists had gathered in Charlottesville to protest the removal of a statue of a civil war era General Robert E. Lee, who fought for the pro-slavery Confederacy.
The protest was in response to a "Unite the Right" white supremacist rally held in Charlottesville.
Fields and his mother Samantha Bloom had moved from Kentucky to nearby OH in recent months, according to U.S. media reports. Fields Jr. remain in jail following his first court appearance on Monday.
Fields entered the Army for a short period of just under four months in 2015.
In those remarks, he did not single out white supremacists or any other hate group.
Fields, 20, of OH, is facing charges including second-degree murder, malicious wounding and hit-and-run.

For now, the only change in that should be to increase the sanctions' severity and target them more accurately at Maduro himself. Venezuela's Ministry of Communication and Information said Sunday that it could not respond to media queries until today.
Fields also wrote a deeply researched paper about the Nazi military during the Second World War, Weimer said.
The next scheduled court hearing is August 25, though Fields' attorney could request a bond hearing before then. Heyer and other protesters were there to show their opposition to the racism.
Fields had been photographed hours before the auto attack carrying the emblem of Vanguard America, one of the white supremacist hate groups that organised the "take America back" campaign sparked by the removal of a Confederate statue.
In a Twitter post, the group said it had handed out the shields "to anyone in attendance who wanted them", and denied Fields was a member.
President Donald Trump addressed the nation Monday morning following the attack.
A federal civil rights investigation into the ramming has been launched, and Attorney General Jeff Sessions said the probe "will have the full support of the Department of Justice".
