Karen Read 's second murder trial is now underway. But this trial is not it for Read's legal troubles. Read, 45, is accused of killing her boyfriend, Braintree native and Boston police officer John O'Keefe outside a Canton home in January 2022. Read's first trial in O'Keefe's death ended in a mistrial in July.

The high-profile Karen Read trial is back in Norfolk Superior Court in Dedham, Massachusetts on Thursday for a full day of witness testimony. Judge Beverly Cannone is expected to start the day by deciding if the prosecution will be allowed to play clip Read's recent documentary appearance for jurors.
