Karen Read is expected back in a Massachusetts court today to face a second murder trial in the death of her Boston police officer boyfriend in a case that has rallied pink-wearing supporters to her cause in their belief of a vast criminal conspiracy.

Read, 45, has pleaded not guilty to second-degree murder, vehicular manslaughter while intoxicated and leaving the scene of a collision resulting in death.

The case stems from the death of her boyfriend, Boston police officer John O’Keefe, whose body was found bruised and battered in the snow in January 2022 outside the home of a fellow officer in the suburb of Canton, Massachusetts.

Her murder trial last year ended in a mistrial after the jury deadlocked on the charges and reported it could not come to a unanimous verdict.

Read’s retrial began April 1 with jury selection. Opening statements are set to begin today, and the trial is expected to last about six to eight weeks.
