Tapes of the grand jury’s deliberations in the case of a black American woman killed in a police operation at her home in Kentucky are to be made public.
Breonna Taylor’s death in March has become a key issue in protests over police brutality and racism.
The jury decided no officers should be charged over her death. Its tapes are secret, but one juror sued for release.
Kentucky’s attorney general said he was confident the tapes would show his team had presented a “thorough case”.
Ms Taylor, an emergency medicine worker, was shot dead when officers stormed her Louisville home on 13 March. They were executing a search warrant as part of a drugs investigation, but no drugs were found in the property.
Last week one officer was charged with wanton endangerment for firing shots into an adjoining apartment, but no-one was charged in connection with Ms Taylor’s death.
Her death and the subsequent decision not to charge any officer with murder or manslaughter have led to repeated Black Lives Matter protests in Louisville and elsewhere.
Why are the tapes being released?
Kentucky Attorney General Daniel Cameron said in a statement that although the grand jury was meant to be a secretive body, “it’s apparent that the public interest in this case isn’t going to allow that to happen”.
He said he was complying with a judge’s order “to release the recording on Wednesday”.
Mr Cameron said: “Once the public listens to the recording, they will see that over the course of two-and-a-half-days, our team presented a thorough and complete case to the grand jury.”
It follows a lawsuit by one member of the grand jury calling for the proceedings to be made public.
The unnamed grand juror sued for release of the tapes following comments made in public by Mr Cameron following the jury’s decisions.
The grand juror’s lawsuit contests some of his statements and says the jurors were used as “a shield to deflect accountability and responsibility”.
A lawyer for Breonna Taylor’s family had also demanded the release of the tapes. Ben Crump, who last week protested outside the grand jury building in Louisville with Ms Taylor’s relatives, said: “There seems to be two justice systems in America. One for black America and one for white America.”
What did the jury decide?
Mr Cameron said he believed that evidence presented to the jury showed that officers Jonathan Mattingly and Myles Cosgrove were justified in opening fire because Kenneth Walker, Ms Taylor’s boyfriend, had shot at them.
He said: “For that reason, the only charge recommended was wanton endangerment.”
Former detective Brett Hankison was charged on three counts and has pleaded not guilty.
Under Kentucky law, someone is guilty of wanton endangerment if they commit an act that shows “an extreme indifference to the value of human life”.
