DEDHAM, Mass. (WPRI) — The second day of jury selection for Karen Read's second murder trial wrapped up with seven jurors being seated on Wednesday. The seven chosen jurors, four men and three women, were picked out of a pool of 91 potential jurors. Of those potential jurors, 78 admitted to kno wing about the case, 40 had already formed an opinion and 16 confessed being biased toward either side. The judge overseeing Read's second trial expects jury selection to take quite some time since it is such a high-profile case. The court is looking to seat 16 jurors total, of which 12 will end up deliberating and four will serve as alternates. BACKGROUND: Jury selection underway for Karen Read’s second murder trial "I feel good. I always feel good. I always feel optimistic. I have faith. I have great support. I have great attorneys. I have the truth," Read told 12 News outside the courthouse. Read is accused of ramming into her then-boyfriend, John O’Keefe, with her SUV and leaving him for dead in a snowstorm back in January 2022. She has been charged with second-degree murder, manslaughter and leaving the scene of a crime. Her first murder trial ended in a mistrial last July after jurors were unable to reach a unanimous verdict. Read's defense attorneys have repeatedly argued that she’s the victim of a sloppy investigation and extensive law enforcement cover-up. Specifically, her attorneys believe she is being framed to protect the three men who are believed to actually be responsible for O’Keefe’s death. During this retrial, Read's supporters are being kept hundreds of extra feet from the courthouse in Dedham, Massachusetts, outside a designated buffer zone. An independent audit into the Canton Police Department was also released on Tuesday, which determined there were mistakes made when police were investigating O'Keefe's death. RELATED: Former Karen Read investigator fired by Mass. State Police The report said the responding officers should have photographed O'Keefe's body at the original location. It also said the interviews of critical witnesses should have taken place at police headquarters with a recording. It also found that Massachusetts State Police and Canton police should have maintained a presence at the home until a secondary search was conducted. It's unclear if the defense or prosecution will use any elements of the report in the trial.
