(CNN) -- The three White men convicted of murdering Ahmaud Arbery pursued him in a fit of illegal vigilantism -- and they did it because they saw "a Black man in their neighborhood and assumed the worst of him," a prosecutor said in closing arguments of their federal hate crimes trial.

"This wasn't about trespassing. This wasn't about neighborhood crimes, either. ... It was about race -- racial assumptions, racial resentment, and racial anger," Justice Department civil rights division counsel Christopher J. Perras told a jury in court Monday morning in Brunswick, Georgia.

Defendants Travis McMichael, his father Gregory McMichael, and their neighbor William "Roddie" Bryan knew only this for certain when they saw Arbery running in their neighborhood in February 2020 outside Brunswick -- that Arbery "was a Black man running down a public street," Perras said.

Perras zeroed in on testimony showing all three talked about Black people in derogatory terms and with racial slurs, including in texts and social media, and argued evidence showed the McMichaels associated Black men with criminality.

"(The McMichaels didn't pursue) because they were concerned about trespassing, unless something extra was motivating them. ... (It was) pent-up racial anger," Perras said.

The McMichaels and Bryan were convicted in a state court in November of felony murder and other charges for the killing of Arbery, a Black man, after they chased him in a neighborhood outside Brunswick.

The jury in the federal trial will decide whether Arbery was killed because of the color of his skin. The three men are each charged with interference with rights -- a hate crime -- and attempted kidnapping. The McMichaels also face charges related to the use of firearms during a violent crime.

The defendants' attorneys were due to give their closing arguments from late Monday morning into the afternoon.

The defendants, who pleaded not guilty in this trial, are already serving life sentences in prison for the murder convictions, though Bryan is eligible for parole after serving 30 years. Convictions in this trial could bring steep fines and more life sentences.

Federal prosecutors and Arbery's family have said he was out for a jog when he was killed. Defense attorneys in both trials contended the McMichaels, suspecting Arbery of trespassing multiple times at an under-construction home, pursued him through neighborhood streets to stop him for police. Travis McMichael argued he shot Arbery in self-defense as they wrestled over McMichael's shotgun.

Bryan had pursued Arbery with his own vehicle and recorded video of the pursuit and shooting.

Prosecutors at both trials conceded Arbery was at the construction site several times including the day of the shooting, but always without breaking in or taking anything, and never doing anything that would allow the men to pursue or stop him. They argued that White people visited the site apparently without being chased, and that the pursuers did not actually see Arbery at the site that day and had no knowledge he'd committed a crime.

Monday's closing arguments came after four days of testimony from 21 witnesses -- only one of which was for the defense.

Prosecutor raises evidence of racial slurs and animus

Perras contrasted the defendants' actions to others in the neighborhood, including a neighbor who, instead of chasing Arbery, simply called a non-emergency police line after seeing him at the construction site.

That was vigilance, whereas the defendants were vigilantes, Perras said.

Arguing the McMichaels acted out of racial resentment, Perras pointed to testimony about the way they talked about African Americans.

Perras brought up a witness who testified that Gregory McMichael, after she brought up the death of a civil rights leader, said in 2015, "All these Blacks are nothing but trouble; I wish they'd all die," before going on a longer rant about Black people.

The prosecutor also pointed to Travis McMichael's use of social media. Testimony had included that Travis McMichael commented under a Facebook video appearing to show a group of primarily Black teenagers beating a White teen, referring to them as "monkeys," and writing: "I say shoot them all."

Perras said evidence showed Travis McMichael projected hatred of Black people onto Arbery. When Travis McMichael's gun was stolen from the neighborhood well before the fatal February 2020 encounter, evidence showed he blamed that on the Black person who'd been reported at the construction site.

There was no evidence any such person had taken McMichael's gun, and he ignored evidence that a White person had allegedly stolen a gun from a vehicle down the street weeks beforehand, Perras said.

Perras also pointed to evidence that Bryan posted racist messages, and argued Bryan's pursuit of Arbery -- after seeing Arbery running from the McMichaels' truck -- was based on race, citing testimony that Bryan didn't know precisely what was happening or asked what the pursuit was about.

"He didn't ask Ahmaud, 'Are you OK.' ... (He assumed) the Black man was in the wrong and the White guys were in the right. ... That's how hard-wired his racial assumptions were," Perras said.

Defense attorneys have acknowledged their clients used racist language, but have denied Arbery's race motivated his killing or their actions toward him.

The jury is made up of eight White jurors, three Black jurors and one Hispanic juror, according to details provided in court. Three White people and one Pacific Islander have also been selected as alternates.

Previous testimony

The defense argued at the state murder trial that the pursuit began when the elder McMichael saw Arbery running from the direction of the under-construction home, and that he believed he matched the description of someone who'd been recorded there previously -- and of someone Travis McMichael had encountered and called police about 12 nights earlier.

Unbeknownst to the McMichaels on the day of the shooting, a neighbor had just called police to report that Arbery was at the construction site alone, and that Arbery ran as the neighbor called, according to testimony.

The prosecution in the murder trial conceded surveillance videos did show Arbery at the construction site multiple times, including the day he was killed, but said that he never broke in or took anything.

During the November trial, witnesses testified that the McMichaels did not know for certain that Arbery was at the site that day, or whether the man in the videos had ever taken anything.

At this month's hate crimes trial, a police officer testified the site's owner had called police several previous times about surveillance video showing people on his property -- including a Black man and, separately, a White couple.

The officer testified that while patrolling the neighborhood in December 2019, he showed video and photos of the incidents to Gregory McMichael, because he knew McMichael from his time as an investigator for the country district attorney's office.

When a prosecutor asked the officer whether he thought McMichael would chase anyone if he saw someone from the video, the officer said no.

In opening statements for the hate crime trial, a prosecutor said the defendants previously used racist language and followed Arbery because of their perceptions of Black people.

"At the end of the day, the evidence in this case will prove that if Ahmaud Arbery had been White, he would have gone for a jog, checked out a cool house under construction, and been home in time for Sunday supper," Assistant US Attorney Barbara Bernstein told the jury last week. "Instead, he went out for a jog and ended up running for his life."

The defendants' attorneys, making separate opening statements last week, acknowledged the men had used racist language -- but said that their actions toward Arbery were not related to race.

"Greg and Travis McMichael followed Ahmaud Arbery not because he was a Black man, but because he was the man who had been illegally entering the house that was under construction," A.J. Balbo, Gregory McMichael's defense attorney, said last week.
