The questioning dragged on all day and into the evening as lawyers queried hundreds of prospective jurors for potential bias in the trial of Amber Guyger, the white Dallas police officer who fatally shot a black neighbor in his own living room.
Finally, the judge sent everyone home except the attorneys, who made their final selections in private.
It wasn't until jurors filed into the courtroom for opening statements that the public got its first look at something many had hoped for: a panel that was as racially diverse as Dallas County.
On Wednesday, the jury composed largely of people of color and women sentenced Guyger to 10 years in prison, a day after convicting her of murder in the September 2018 killing of her upstairs neighbor, Botham Jean, after she said she mistook his apartment for her own.
"This trial had a magnifying glass on it," and jury selection was a fairer process because of that, said Alex Piquero, a criminologist at the University of Texas at Dallas. He said prosecutors and defense attorneys likely realized there would be a huge public outcry if the jury turned out mostly white.
"There were so many different eyes looking at this case, it was hard not to play by the rules," he said.
Guyger, 31, was still in her police uniform after a long shift when she shot Jean, a 26-year-old accountant from the Caribbean island nation of St. Lucia, after pushing open the unlocked door to his apartment. She was soon fired from the force and charged with murder.
She testified at her trial that she mistook Jean's home for her own, which was one floor below, and thought he was a burglar.
From the beginning, the jury's demographics were bound to be closely watched in a case that ignited debate over race and policing. Critics, including Jean's family, questioned why Guyger was not taken into custody immediately after the shooting and whether race played a factor in her decision to use deadly force.
Research suggests that more diverse juries make decisions differently than all-white juries, said Samuel R. Sommers, a Tufts University professor who has studied jury diversity. For example, an all-white jury is more likely to convict a black defendant.
"Race and ethnicity influence our perceptions and judgment all the time in our daily lives," he said. "Nothing makes those biases disappear when we enter a jury room."
Guyger's attorneys tried unsuccessfully to get the trial moved to another county, arguing that pretrial publicity made a fair trial in Dallas County impossible. Moving the trial to a suburban county also would have all but guaranteed a whiter, more conservative jury, which could have led to a different outcome, experts said.
Dallas County is about 29% non-Hispanic white.
While awaiting the jury's sentence, an attorney for Jean's family, Ben Crump, said the panel's diversity would help them "see past all the technical, intellectual justifications for an unjustifiable killing."
But another Jean family attorney, Daryl Washington, said Thursday that the jury also represented Guyger because it included eight women.
"It was very important to have jurors representative of the county they served in ... but this wasn't just about black and white," Washington said.
Some outside court reacted angrily Wednesday to Guyger's 10-year sentence, arguing it was too lenient. Prosecutors had asked for 28 years, Jean's age if he were still alive.
But two jurors who spoke to ABC News said the panel tried to consider what Jean would have wanted, saying they were moved by testimony from Jean's family and friends, who described his deep faith and caring nature.
"We all agree that (the shooting) was a mistake, and I don't think (Jean) would want to take harsh vengeance," said one of the jurors, a white man who wasn't named by the network.
The other juror, a black woman, said her reaction to prosecutors' sentencing request was: "I can't give her 28 years."
"I know a lot of people are not happy," but she felt this case was different from those of other unarmed black men killed by police in recent years.
"Those officers that killed unarmed black men, when they got out, they went back to living their lives," she said. "Amber Guyger, ever since she killed that man, she has not been the same. She showed remorse and that she's going to have to deal with that for the rest of her life."
One of Guyger's lawyers and the president of the Dallas Police Association, which paid for her legal defense, did not respond to calls and text messages seeking comment Wednesday and Thursday.
Prosecutors historically have tried to get all-white juries because they were more likely to support law enforcement, said Kerri Anderson Donica, president of the Texas Criminal Defense Lawyers Association.
"I think it's so ingrained in prosecutors' minds that it's probably a bias they don't even realize exists," said Donica, who is white.
Former Dallas County prosecutor Heath Harris, who is black, said all attorneys seek jurors who will "rule how you want." Harris, now a defense attorney, said it's just as common for attorneys of minority clients to try to limit conservative white jurors. And though he believes Guyger would probably have been acquitted if the trial were held elsewhere, he thought there was enough evidence to justify either an acquittal or conviction.
The case also illustrates how much Dallas County has changed.
A 1986 Dallas Morning News investigation found that prosecutors routinely manipulated the racial makeup of juries through legal challenges, excluding up to 90% of qualified black candidates from felony juries. The U.S. Supreme Court had ruled that jurors could not be excluded solely based on race.
The newspaper also cited a treatise on jury selection written in the 1960s and credited to a Dallas County assistant district attorney. It advised prosecutors to not allow any minorities on a jury "no matter how rich or how well-educated."
Community activist Changa Higgins, who leads the Dallas Community Police Oversight Coalition, said he was still shocked when the Guyger jury returned a conviction.
"This is one of the very few times I've seen the justice system work the way it's supposed to work for us, or the way it works for white people," he said.
