A jury on Wednesday acquitted a white Oklahoma police officer in the shooting death of an unarmed black man in Tulsa last year.
Tulsa police officer Betty Shelby, 43, had been charged with manslaughter in the September 2016 shooting death of Terence Crutcher, 40, during an encounter that began with the report of a stalled vehicle.
The district attorney’s office announced a verdict had been reached shortly after 9 p.m. local time (10 p.m. ET), more than eight hours after deliberations began, NBC affiliate KJRH reported.
The manslaughter trial against Shelby opened May 10 with prosecutors laying out how the five-year veteran of the Tulsa Police Department encountered Crutcher — what should have been a routine traffic matter that went too far, they said.
Instead, Crutcher's death — another involving an unarmed black man at the hands of police — touched off Black Lives Matter protests and calls for greater transparency from local authorities.
Crutcher's family called the verdict a disappointment, and called the police department "corrupt" after being led out of the courtroom filled with emotion. Crutcher’s twin sister, Tiffany Crutcher, said her brother's hands were up, that he was not an imminent threat or attack her and didn't deserve to be shot.
"Terence was not the aggressor; Betty Shelby was the aggressor," she said. "Betty Shelby had the gun. Betty Shelby was following him with his hands up."
Shelby was among the officers who responded to reports of a stalled SUV left abandoned in the middle of a road just after 7:30 p.m. local time, prosecutors said.
Police said Crutcher approached the vehicle but failed to listen to commands from officers. Shelby asked Crutcher if the car was his, but only mumbled to himself and didn't respond, according to an affidavit.

Crutcher was seen walking to his car with his hands up before reaching into the driver's side window. One of the officers fired his Taser at him. Shelby also fired her gun — striking the father of four in the lung, police said.
Video footage taken from helicopter and cruiser dashcams don't provide clear views of the moment she shot him.
A toxicology report revealedthat Crutcher was on two hallucinogenic drugs, including PCP, during the encounter. It took at least two minutes after Crutcher was shot before police attempted aid, according to officers.
During the trial, Shelby testified that police training videos taught her to be careful about suspects pulling guns when they reach into their vehicles, according to The Associated Press.
She fired her weapon, she told a Tulsa County courthouse on Monday, because "I feared for my life."
"I did everything I could to stop this," she added. "Crutcher's death is his fault."
Prosecuting attorney Kevin Gray told the court that Crutcher was never aggressive toward police or actually produced a gun, and that Shelby was merely "guessing" that he had one.
Her defense attorney, Shannon McMurray, argued that it was unfair for the prosecution to repeatedly say Crutcher was unarmed. No weapon was found inside the SUV.
"To somehow imply that she was supposed to see what was in this door panel is absurd. It's deceitful and you should disregard it," McMurray told jurors, according to the AP.
Judge Doug Drummond, however, said his being unarmed was a relevant factor in the case.
An attorney for the Crutcher family, Benjamin Crump, raised the deaths of other black men in encounters with police, like Michael Brown and Freddie Gray, in expressing his disappointment with the verdict.
"The list just goes on and on, of unarmed African American men being killed by white police officers, and they get away with it," Crump said.
Jerad Lindsey, chairman of Tulsa Fraternal Order of Police, said that the jury’s verdict was the right one, but said the shooting was a tragedy. "There’s no winners in this," he said. "There's still a family that has dealt with a tragedy here, the Crutchers, and we still extend our deepest sympathies to them."
"And now that we’ve reached a verdict, Tulsa’s gonna have to figure out how to get its arms around this and be able to move forward in a positive way," Lindsey said.
Both Shelby's family, including her husband, who is a fellow Tulsa police officer, and Crutcher's family have been at the courthouse since the trial began.
Shelby was placed on paid administrative leave amid the investigation, then on unpaid leave. Shelby did not speak to the media after Wednesday's verdict. McMurray said Shelby is "elated and very proud of her jury."
Tulsa County District Attorney Stephen Kunzweiler in a statement Wednesday night thanked jurors and said "there can be no doubt that the decision rendered by this jury was only after a long and deliberative process."
The NAACP Legal Defense Fund in a statement called Wednesday’s verdict disappointing, and said it is hopeful the Justice Department files charges. The DOJ announced shortly after the shooting that it was opening a civil rights investigation.
