Karen Read is accused of manslaughter in the death of her boyfriend, John O'Keefe. The prosecution's case relies on a timeline showing Read's heavy drinking and erratic behavior the night O'Keefe died, along with physical evidence linking her car to the scene. However, the defense argues that new evidence, including a Google search on a witness's phone suggesting foul play by others, points to a different conclusion. The defense alleges a cover-up involving police and contends that O'Keefe's injuries indicate a fight, contradicting the initial autopsy report. The case hinges on conflicting accounts, forensic evidence, and the credibility of witnesses.
