(CNN) Derek Chauvin, the former police officer who killed George Floyd on a Minneapolis street last year, was sentenced Friday to 22 and half years in prison.
Chauvin, in a light gray suit and tie and white shirt, spoke briefly before the sentence was imposed, offering his "condolences to the Floyd family."
Under Minnesota law, Chauvin will have to serve two-thirds of his sentence, or 15 years -- and he will be eligible for supervised release for the remaining seven and a half years.
The sentence exceeds the Minnesota sentencing guideline range of 10 years and eight months to 15 years for the crime. Floyd's death sparked massive protests across the nation over police brutality.
Judge Peter Cahill said the sentence was not based on emotion or public opinion. He wanted to "acknowledge the deep and tremendous pain that all of the families are feeling, especially the Floyd family," the judge said.
In a 22 page memorandum, Cahill wrote that two aggravating factors warranted a harsher sentence -- that Chauvin "abused his position of trust or authority" and treated Floyd with "particular cruelty." Chauvin, the judge wrote, treated Floyd "without respect and denied him the dignity owed to all human beings."
Cahill said the former officer "objectively remained indifferent to Mr. Floyd's pleas' even as Mr. Floyd was begging for his life and obviously terrified by the knowledge that he was likely to die."
"Mr. Chauvin's prolonged restraint of Mr. Floyd was also much longer and more painful than the typical scenario in a second-degree or third-degree murder or second-degree manslaughter case," the judge wrote.
Chauvin will remain in a restricted housing unit separated from the general population at the Minnesota Correctional Facility- Oak Park Heights "for the time being," Minnesota Department of Corrections spokesperson Sarah Fitzgerald told CNN.
"His ultimate placement is undetermined, but his safety will be our predominate concern when determining final placement," Fitzgerald said, adding Chauvin has been on administrative segregation status for his "general safety."
Chauvin, 45, was convicted in April on charges of second-degree unintentional murder, third-degree murder and second-degree manslaughter for his role in Floyd's death.
Floyd's final moments, captured on searing cell phone footage by a 17-year-old, illustrated in clear visuals what Black Americans have long said about how the criminal justice system treats Black people. Floyd's death set off mass protests across the globe as well as incidents of looting and unrest.
At the intersection of Chicago Avenue and 38th Street in Minneapolis, where Floyd took his last breaths, people watched the hearing on mobile phones.
Outside the court complex, Floyd supporters expressed mixed emotions about the prison term.
Floyd's sister, Bridgett, who founded the George Floyd Memorial Foundation, said in a statement that the sentence "shows that matters of police brutality are finally being taken seriously."
"However, we have a long way to go and many changes to make before Black and brown people finally feel like they are being treated fairly and humanely by law enforcement in this country," she added.
Floyd family attorney Ben Crump, in a statement, said the "historic sentence" brings the family and country "one step closer to healing by delivering closure and accountability."
"With Chauvin's sentence, we take a significant step forward -- something that was unimaginable a very short time ago," he said.
Minnesota Attorney General Keith Ellison told reporters he hoped "this moment gives us pause and allows us to rededicate ourselves to the real societal change that will move us much further along the road to justice."
"My hope is that he takes the time to learn something about the man whose life he took and about the movement that rose up to call for justice in the wake of George Floyd's torture and death," he said of Chauvin. "Today is also an important moment for our country. The outcome of this case is critically important. But by itself, it's not enough."
Chauvin's defense attorney, Eric Nelson, declined to comment.
After members of Floyd's family delivered victim impact statements, Chauvin stepped to the lectern beside his lawyer and said, "I want to give my condolences to the Floyd family." He said pending legal matters prevented him from saying more.
The victim impact statements included an emotional video from Floyd's 7-year-old daughter, Gianna, who wore a bow wrapped around her hair.
"I ask about him all the time," the little girl said, responding to questions about her dad.
"I miss you and I love you," she said when asked what she would tell her father.
Chauvin, wearing a face covering, listened from the defense table.
Floyd's two brothers and a nephew spoke about the birthday parties, graduations and other family milestones he will miss.
Philonise Floyd said he has nightmares in which he hears his brother pleading for his life and calling out for their mother. He said he relives the video of his brother "being tortured to death" by Chauvin, especially the smirk on the former cop's face.
"My family and I have been given a life sentence. We will never get George back," he said.
Philonise wiped tears from his eyes as he spoke about Gianna. Terrence Floyd, another brother, struggled to speak as he asked for the maximum penalty.
"We don't want to see no more slaps on the wrist," nephew Brandon Williams said. "We been through that already -- in my community, in my culture."
Carolyn Pawlenty, Chauvin's mother, grew emotional as she described him as her favorite son and "a good man." She said the happiest moments in her life were when Chauvin was born and when she pinned his badge on his uniform for the first time.
"Derek, I want you to know I've always believed in your innocence, and I will never waver from that," she said.
Chauvin's post-verdict motion for a new trial was denied by Cahill hours before the hearing.
Cahill ruled Thursday night that Chauvin "failed to demonstrate ... the Court abused its discretion or committed error such that Defendant was deprived of his constitutional right to a fair trial."
Cahill also ruled that Chauvin failed to demonstrate prosecutorial or juror misconduct.
Defense attorneys had argued that "errors, abuses of discretion, prosecutorial and jury misconduct" made the trial unfair.
State prosecutors had requested a 30-year prison sentence, saying it "would properly account for the profound impact of Defendant's conduct on the victim, the victim's family, and the community," according to a sentencing memo.
Nelson argued for probation and time served, or at least a sentence less than what the law guides.
"Mr. Chauvin asks the Court to look beyond its findings, to his background, his lack of criminal history, his amenability to probation, to the unusual facts of this case, and to his being a product of a 'broken' system," Nelson wrote in a filing.
The guilty verdict on all three charges against Chauvin came nearly a year after he impassively kneeled on the neck and back of Floyd, handcuffed and lying prone on the street, for 9 minutes and 29 seconds. Under the officer's knees, the 46-year-old Black man gasped for air, repeatedly exclaimed "I can't breathe" and ultimately went silent as a group of horrified bystanders looked on.
Chauvin arrived at the court complex in downtown Minneapolis hours before his sentencing.
Three other officers who were on scene during Floyd's fatal arrest -- Tou Thao, Thomas Lane and Alexander Kueng -- have pleaded not guilty to charges of aiding and abetting. Their trial is currently set for March 2022.
Since his conviction, Chauvin has been held at Minnesota Correctional Facility-Oak Park Heights, outside of Minneapolis, and was put into a segregated housing unit for his own safety, a prison spokesperson said. The Minnesota Department of Corrections will decide on where Chauvin will serve his time after receiving Cahill's sentencing order, spokeswoman Sarah Fitzgerald told CNN.
Legally, Chauvin could have faced up to 40 years in prison for second-degree murder, up to 25 years for third-degree murder and up to 10 years for manslaughter. The second-degree murder charge said Chauvin assaulted Floyd with his knee, which unintentionally caused Floyd's death. The third-degree murder charge said Chauvin acted with a "depraved mind," and the manslaughter charge said his "culpable negligence" caused Floyd's death.
Chauvin has no prior criminal record, so Minnesota's sentencing guidelines recommend about 12 and a half years in prison for each murder charge and about four years for the manslaughter charge.
In this case, state prosecutors asked for a tougher sentence than the recommendations provide, citing five aggravating factors they said applied. Cahill had ruled that four of the five factors were proven beyond a reasonable doubt: (1) Chauvin abused a position of trust and authority, (2) he treated Floyd with particular cruelty, (3) children were present during the offense, and (4) Chauvin committed the crime as a group with the active participation of at least three other people.
The findings allowed the judge to sentence Chauvin beyond the guidelines.
Over about three weeks of testimony in court, Minnesota prosecutors repeatedly told jurors to "believe your eyes" and rely on the infamous video of Floyd.
"This case is exactly what you thought when you saw it first, when you saw that video. It is exactly that. You can believe your eyes," prosecuting attorney Steve Schleicher said in closing arguments. "This wasn't policing. This was murder."
The defense called seven witnesses -- but not Chauvin himself, as he invoked his Fifth Amendment right not to testify. Nelson argued that Chauvin's use of force was reasonable, that he was distracted by hostile bystanders and that Floyd died of other causes.
Chauvin faces other legal issues as well. A federal grand jury indicted all four former officers in connection with Floyd's death, alleging they violated his constitutional rights, according to court documents filed in federal court in Minnesota. They are due to be arraigned on the charges in September, according to a court filing.
Chauvin also was charged in a separate indictment related to an incident in which he allegedly used unreasonable force on a Minneapolis 14-year-old in September 2017, the Justice Department said in a statement. He is also expected to be arraigned in that case in September, according to court filings.
