The Karen Read trial is back in court Tuesday for a sixth day of witness testimony. Key witness Jen McCabe is now on the stand after a cellphone expert finished his testimony about her disputed Google search and John O'Keefe's movements the night of his death.

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.
