Now, after an extensive 4-year investigation by the FBI, 10 young people have been convicted for their roles in the murder of James Craig Anderson, a 49-year-old auto plant worker, and other similar racial attacks on victims that appeared homeless or intoxicated.

The latest guilty pleas came Wednesday in U.S. District Court in Jackson, Miss.

John Louis Blalack, 20, of Brandon, Miss., pleaded guilty to two counts of violating the Matthew Shepard and James Byrd Jr. Hate Crimes Prevention Act. Robert Henry Rice, 24, also from Brandon, pleaded guilty to one count of violating the act.

The statutory maximum sentence for these violations is 10 years in prison and a $250,000 fine. Sentencing for Blalack is set for April 23 and sentencing for Rice is set for April 30.

The case went all the way to the desk of U.S. Attorney General Eric Holder, who released a statement today about the 10 arrests and convictions, calling it a “landmark case.”

“Justice has been served,” Holder said. “The hate crimes to which these defendants have pleaded guilty were as shocking as they were reprehensible—targeting innocent people for racially-motivated acts of violence that inflicted grievous harm and even claimed a life.”

Holder went on to say the Justice Department “will never rest in our pursuit of those who victimize their fellow citizens.”

“This landmark case should send a clear message: that anyone who commits an act of bias-motivated violence, or who violates the civil rights to which all Americans are entitled, will be held accountable to the fullest extent of the law,” Holder said.

Previously, Deryl Paul Dedmon, 22; John Aaron Rice, 21; Dylan Wade Butler, 23; Jonathan Kyle Gaskamp, 22; and Joseph Paul Dominick, 23, all from Brandon, and William Kirk Montgomery, 25, from Puckett, Miss., Shelbie Brooke Richards, 21, from Pearl, Miss., and Sarah Adelia Graves, 21, from Crystal Springs, Miss., pleaded guilty in connection with their roles in these offenses.

The FBI investigation revealed that beginning in the spring of 2011, Blalack, Robert Rice and others conspired with one another to harass and assault African-American people in and around Jackson.

On various occasions, the racist gang of young people “used dangerous weapons, including beer bottles, sling shots and motor vehicles, to cause, and attempt to cause, bodily injury to African-American people,” the Justice Department statement said.

The attackers “would specifically target African Americans they believed to be homeless or under the influence of alcohol because they believed that such individuals would be less likely to report an assault. The co-conspirators would often boast about these racially motivated assaults,” the statement said.

The attack on Anderson occurred after Blalack and others attended a birthday party and bonfire for a friend in Puckett, Miss. During the party, Blalack and others talked about going to Jackson to harass and assault African-American people, Justice Department officials said.

In the early morning hours of June 26, 2011, Blalack, Montgomery, Dedmon, John Aaron Rice, Butler, Richards and Graves agreed to carry out their plan to find, harass and assault African-American people. Robert Rice did not accompany his friends on that trip to Jackson.

At around 4:15 a.m., Blalack, Montgomery, John Aaron Rice, and Butler drove to Jackson in Montgomery’s white Jeep with the understanding that Dedmon, Richards and Graves would join them a short time later. Blalack and the other three occupants of the Jeep then drove around Jackson and threw beer bottles from the moving vehicle at African-American pedestrians.

At approximately 5:00 a.m., Blalack and the other three occupants in the Jeep spotted Anderson in a motel parking lot. The occupants of the Jeep decided that Anderson would be a good target for an assault because he was African-American and appeared to be visibly intoxicated, the Justice Department statement said.

Blalack and John Aaron Rice decided to get out of the Jeep to distract Anderson while they waited for Dedmon, Richards and Graves to arrive.

After Dedmon, Richards and Graves arrived in Dedmon’s Ford F250 truck, Dedmon and John Aaron Rice physically assaulted Anderson. Rice first punched Anderson in the face, knocking Anderson to the ground, and then Dedmon punched Anderson in the face multiple times while he was on the ground.

After the assault, Blalack, Montgomery, Rice and Butler left the motel parking lot in the Jeep. As they left, one of the occupants of the Jeep yelled, “White Power!” Prior to getting back into his truck, Dedmon responded by also yelling “White Power!”

“Once back in his Ford F250 truck, Dedmon deliberately used his vehicle to run over Anderson, causing injuries which resulted in his death,” the Justice Department statement said. Blalack’s guilty plea includes his role in that offense.

On a previous occasion, the Justice Department said, Blalack, Montgomery, Butler and Dominick drove around west Jackson to find and assault African Americans. Blalack and the other occupants of the vehicle purchased bottles of beer to drink and then threw the beer bottles at African Americans.

The occupants of the vehicle also purchased a sling-shot and used it “to shoot metal ball bearings out of the moving vehicle at African American pedestrians,” the statement said. Blalack pleaded guilty for his role in this offense.

Another racially motivated assault involving members of the gang occurred at or near a golf course in Jackson. On that evening, Robert Rice, Blalack, Montgomery, Gaskamp, Dedmon and John Aaron Rice were in a vehicle again searching for “vulnerable African-American men to assault,” the statement said.

When a potential victim was spotted, Dedmon, John Aaron Rice and Gaskamp got out of their vehicle and chased the victim down. “The three men beat the man to the point that he begged for his life,” the Justice Department said. Investigators did not disclose if that victim was ever located or identified. Robert Rice’s guilty plea included his role in that offense.
