The suspects in the Tulsa, Okla., shooting spree were arraigned on Monday, and pleas of not guilty were entered for both defendants Jake England and Alvin Watts.
England, 19, and Watts, 33, have been accused of shooting five people -- fatally wounding three - in a racially-motivated attack on carried out on April 6.
The Associated Press reported that the two suspects were arraigned via closed circuit television in Tulsa County District Court. They have been charged with first-degree murder, shooting with the intent to kill and malicious intimidation or harassment.
The harassment charges were filed because it is believed that the victims were targeted because of their color.
Authorities have speculated that the shootings may have been carried out to avenge the death of England's father. Police have told the media that England's father was shot and killed in self-defense by a black man in 2010.
A Facebook page believed England's contained some racial slurs the day before the shootings.
Today is two years that my dad has been gone, shot by a f------ n-----. It's hard not to go off between that and Sheran. I'm gone in the head, the post read.
