I am assured not only are we on schedule, we are ahead of schedule,” Judge Beverly Cannone told jurors in the Karen Read retrial.

The second trial of Karen Read, the Massachusetts woman accused of killing her Boston cop boyfriend John O'Keefe, will be delayed until Friday, June 6. The court was adjourned just before 1 p.m. June 4 after a day that largely focused on testimony from the snowplow driver who passed the yard where O’Keefe’s body was found.

The sound of the air conditioning and fans inside Norfolk Superior Court in Dedham have been an issue throughout both of Read's trials. Often during the first trial, when witnesses were testifying, their words could not be heard clearly in the courtroom because of the sound coming from the units, so Cannone ordered them to be turned off.
