The U.S. Supreme Court has denied Karen Read’s petition for certiorari, and therefore will not review her case. Read had asked the Supreme Court to intervene in her case, arguing double jeopardy after the jurors allegedly agreed on acquittal for two charges in her first trial. Read is accused of killing her boyfriend, Boston police officer John O'Keefe, in January 2022. Prosecutors allege Read hit O'Keefe with her vehicle and left him to die as Boston was hit with a major blizzard. Read has denied the allegations and maintained her innocence. Testimony in Read’s retrial -- now in its second week -- resumed Monday morning with testimony from Ian Whiffin, a digital forensics examiner from Cellebrite. The judge declared a mistrial in Read's first trial last year after the jury could not reach a unanimous verdict on all of the counts. She was charged with first-degree murder, manslaughter while operating a motor vehicle under the influence and leaving the scene of a fatal accident. She pleaded not guilty.

The U.S. Supreme Court on Monday denied Karen Read's double jeopardy appeal, which her defense team filed earlier this month. Read's defense team asked the nation's highest court to throw out two of the three charges against her, including second-degree murder, in the death of her boyfriend John O'Keefe, a Boston police officer.

Read is accused of striking her boyfriend, John O'Keefe, with her SUV in 2022 and leaving him to die alone in the snow outside of a house party in Canton, a suburb about 20 miles south of Boston. She has been charged with second-degree murder, manslaughter while operating a vehicle under the influence and leaving the scene. Prosecutors say Read intentionally backed into O'Keefe after she dropped him off at the home of fellow Boston officer Brian Albert and returned hours later to find him dead. The defense says she was a victim of a vast police conspiracy and that O'Keefe was fatally beaten by another law enforcement officer at the party. A mistrial was declared last year after jurors said they were at an impasse, and deliberating further would be futile. Speaking briefly to reporters Tuesday afternoon, Read said she is innocent and praised her legal team.
