Dedmon from Brandon, Mississippi, pleaded guilty to capital murder and hate crime after Mr Anderson, a car plant worker in Mississippi's capital, was killed in June 2011.

Less than 20 seconds later, a Ford truck backs up and then lunges forward and Mr Anderson's shirt is illuminated in the headlights before he disappears under the vehicle next to the curb.

Appearing in court, all three, wearing red prison jumpsuits and shackled at the waist and ankles, took to a podium to apologize to members of Anderson's family for their actions.

Dedmon said: 'I want to tell the Anderson family how truly sorry I am.'

The apologies came after an impassioned condemnation of their actions from Mr Anderson's sister, Barbara.

She said her brother's death came 'at the hands of these strangers with eyes full of hatred.'

She added her brother 'helplessly fought to stay alive' as he was attacked by people he did not know.

Prosecutors said the youths harassed or assaulted black people who they thought were homeless or intoxicated.

Victims were chosen because they thought they would not tell police, authorities said with the harassment beginning in April 2011, culminating in the death of Mr Anderson.

They pleaded guilty in March 2012 to one count of conspiracy and one count of committing a hate crime.

Each was sentenced to five years on the conspiracy count to run concurrent with the other.

In Dedmon's case, U.S. District Judge Carlton Reeves said the federal sentenced would run concurrent with his state sentence.

The judge added: 'What these people did was ugly, painful and sad and criminal.

Before sentencing, he also told the courtroom that the Mr Anderson's death reflected the 'inhumanity of racism' with which Mississippi has dealt throughout its history.

He explained: '"The sad thing is these ... hunts were instigated by our children, these kids.

'The victims were targeted because of their race. These three defendants and others made a joint decision to act on racial hatred.'

Dominick pleaded guilty to conspiracy in 2013 and faces five years in prison.
