A prosecutor said Wednesday that he will charge a white former suburban Minneapolis police officer with second-degree manslaughter for killing 20-year-old Black motorist Daunte Wright in a shooting that ignited days of unrest and clashes between protesters and police.

The charge against former Brooklyn Center police Officer Kim Potter will be filed Wednesday, three days after Wright was killed during a traffic stop and as the nearby murder trial progresses for the ex-officer charged with killing George Floyd last May, Washington County Attorney Pete Orput said. Second-degree manslaughter carries a maximum penalty of 10 years in prison.

Potter was arrested Wednesday morning at the Bureau of Criminal Apprehension in St. Paul. An attorney for Potter did not immediately respond to messages from The Associated Press.

The former Brooklyn Center police chief has said that Potter, a 26-year veteran and training officer, had intended to use her Taser on Wright but fired her handgun instead. However, protesters and Wright’s family members say there’s no excuse for the shooting and it shows how the justice system is tilted against Blacks, noting Wright was stopped for expired car registration and ended up dead.

Potter, 48, resigned Tuesday, as did Police Chief Tim Gannon.

The Star Tribune reported that concrete barricades and tall metal fencing had been set up around Potter’s home in Champlin, a suburb north of Brooklyn Center, with police cars guarding the driveway. After Floyd’s death last year, protesters demonstrated several times at the home of the former Minneapolis officer charged with killing him, Derek Chauvin.

Police say Wright was pulled over for expired tags, but they sought to arrest him after discovering he had an outstanding warrant. The warrant was for his failure to appear in court on charges that he fled from officers and possessed a gun without a permit during an encounter with Minneapolis police in June.

Gannon released Potter’s body camera video the day after Sunday's shooting. It showed her approaching Wright as he stood outside of his car as another officer was arresting him.

As Wright struggles with police, Potter shouts, “I’ll Tase you! I’ll Tase you! Taser! Taser! Taser!” before firing a single shot from her handgun.

Wright family attorney Ben Crump said the family appreciates criminal case, but he again disputed that the shooting was accidental, arguing that an experienced officer knows the difference between a Taser and a handgun.

“Kim Potter executed Daunte for what amounts to no more than a minor traffic infraction and a misdemeanor warrant,” he said

Cases of officers mistakenly firing their gun instead of a Taser do happen, but experts say they are extremely rare, usually less than once a year nationwide.

Transit officer Johannes Mehserle was convicted of involuntary manslaughter and sentenced to two years in prison after responding to a fight at a train station in Oakland, California, killing 22-year-old Oscar Grant in 2009. Mehserle testified at trial that he mistakenly pulled his .40-caliber handgun instead of his stun gun.

In Tulsa, Oklahoma, a white volunteer sheriff’s deputy, Robert Bates, was convicted of second-degree manslaughter after accidentally firing his handgun when he meant to deploy his stun gun on Eric Harris, a Black man who was being held down by other officers in 2015.

Potter was an instructor with the Brooklyn Center police, according to the Minnesota Police and Peace Officers Association. She was training two other officers Sunday when they stopped Wright, the association’s leader, BIll Peters, told the Star Tribune.

In her one-paragraph letter of resignation, Potter said, “I have loved every minute of being a police officer and serving this community to the best of my ability, but I believe it is in the best interest of the community, the department, and my fellow officers if I resign immediately.”

Brooklyn Center Mayor Mike Elliott had said he hoped Potter's resignation would “bring some calm to the community,” but that he would keep working toward “full accountability under the law.”

“We have to make sure that justice is served, justice is done. Daunte Wright deserves that. His family deserves that,” Elliott said.

Police and protesters faced off again after nightfall Tuesday, with hundreds of demonstrators once more gathering at Brooklyn Center’s heavily guarded police headquarters, now ringed by concrete barriers and a tall metal fence, and where police in riot gear and National Guard soldiers stood watch.

About 90 minutes before a 10 p.m. curfew, state police announced over a loudspeaker that the gathering had been declared unlawful and ordered the crowds to disperse. That set off confrontations, with protesters launching fireworks toward the station and throwing objects at officers, who launched flashbangs and gas grenades, then marched in a line to force back the crowd.

State police said the dispersal order came before the curfew because protesters were trying to take down the fencing and throwing rocks at police. The number of protesters dropped rapidly over the next hour, until only a few remained. Police also ordered all media to leave.

Brooklyn Center, a suburb just north of Minneapolis, has seen its racial demographics shift dramatically in recent years. In 2000, more than 70% of the city was white. Today, a majority of residents are Black, Asian or Hispanic.

Elliott said Tuesday that he didn't have at hand information on the police force's racial diversity but that “we have very few people of color in our department.”
