Four US police officers have been arrested and charged over the fatal 2020 shooting of Breonna Taylor.
Taylor was killed in her home in Louisville, Kentucky, by plainclothes police who were executing a "no-knock" search warrant.
The hospital worker, 26, was shot as officers stormed the apartment just after midnight while she was with her boyfriend, Kenneth Walker.
Her death sparked racial injustice protests around the country.
Only one officer involved in the raid - former Louisville detective Brett Hankinson - had been previously charged over the case.
Hankinson, who fired 10 shots during the incident, was acquitted by a jury earlier this year. He is among the four people to face new charges through the US Department of Justice.
The others are Joshua Jaynes, also a former officer, and serving officers Kelly Hanna Goodlett and Kyle Meany.
US Attorney General Merrick Garland announced the new charges. He said the officers were being charged with civil rights offences, unlawful conspiracy, unconstitutional use of force and obstruction.
Garland added that three of the officers - all but Hankinson - had been charged with falsification of a search warrant.
Hankinson is charged with using excessive force when he opened fire during the raid.
"Breonna Taylor should be alive today," Garland told reporters.
The search warrant obtained by police included Taylor's name and address. Authorities suspected her ex-boyfriend, Jamarcus Glover, a convicted drug trafficker, had used her apartment to hide narcotics or money.
No drugs were found at the property, though Jefferson County Prosecutor Thomas Wine said the search had been cancelled after the shooting.
In 2020, the Taylor family sued Louisville police and reached a $US12 million settlement.
Reacting to news of the new charges on Thursday, the family's lawyers said: "Today was a huge step toward justice."
Kenneth Walker shot and wounded one of the police officers in the leg during the raid, taking him for an intruder. He was charged with attempted murder, but the case was dismissed.
Walker said he had fired out of self-defence, and a judge permanently closed the case against him, meaning he cannot ever be charged again over it.
Taylor's death - along with that of two black men, George Floyd in Minnesota and Ahmaud Arbery in Georgia - sparked anti-racism protests across the US and the globe.
