Missouri top prosecutor asked a court Tuesday to put the brakes on releasing a woman from prison in a 1980 killing that her attorneys allege was committed by a now-discredited police officer.

Missouri Attorney General Andrew Bailey also said his office will ask the state appeals court to review a judge’s ruling last week that found Sandra Hemme’s attorneys had established evidence of actual innocence. In that decision, Judge Ryan Horsman wrote that Hemme, who has been imprisoned for 43 years for the murder of library worker Patricia Jeschke, must be freed within 30 days unless prosecutors retry her.
