Karen Read's second murder trial began on Tuesday in Norfolk County Superior Court, focusing on her alleged role in the death of her boyfriend, Boston police officer John O'Keefe, who was found dead outside a home in Canton in January 2022. Read has been charged with second-degree murder, vehicular manslaughter while operating under the influence, and leaving the scene of a collision that caused death. She pleaded not guilty and claims she is a victim of a conspiracy involving law enforcement, asserting her innocence while being retried less than a year after her first trial ended in a mistrial, according to CBS News, HuffPost, and ABC News.

During the opening statements, special prosecutor Hank Brennan emphasized that Read's own statements in media interviews will be critical for the prosecution, suggesting they could show her guilt. Prosecutors allege that Read intentionally struck O'Keefe with her SUV after dropping him off and left him to die in the snow. Brennan indicated that evidence, including DNA from O'Keefe found on Read's vehicle and prior admissions from Read regarding her state of intoxication that night, will support their case. In contrast, defense attorney Alan Jackson argued that Read is unjustly accused and pointed out flaws in the investigation, as the first witness testified about Read's allegedly incriminating statements made at the scene, according to HuffPost, ABC News, and ABC News.

A key witness in the trial, Kerry Roberts, who was a friend of O'Keefe, testified that Read had informed her of O'Keefe's death immediately after it was discovered. However, she framed Read's frantic calls as that of a concerned partner who feared the worst, contradicting the prosecution's interpretation of those calls as admissions of guilt. The relationship dynamics among the witnesses and the police are prominent in this case, with past friendships potentially complicating the evidence presented. Roberts emphasized the victim's narrative, asking people not to forget that O'Keefe is the one who lost his life, highlighting the emotional toll on his family and friends, according to ABC News and HuffPost.

The trial's proceedings are expected to last several weeks and will involve testimony from numerous witnesses, including the former investigator whose motivations have come under scrutiny. He has been described as a "cancer" to the case by the defense, which highlights the contentious atmosphere surrounding the trial. The complexities of legal narratives and public exposure suggest that this case will continue to attract significant media attention and community involvement throughout its duration, as noted by sources such as CBS News and ABC News.
