Karen Read, accused of killing her police officer boyfriend, John O’Keefe, faced a mistrial after a deadlocked jury in her murder trial, with prosecutors planning to retry the case. The defense argued that O’Keefe was killed inside and framed Read, while prosecutors claimed she ran him over and left him. Despite rigorous deliberations, jurors couldn't agree on a verdict, leading to the mistrial declared by Judge Beverly Cannone. The case involved complex issues, 74 witnesses, and 657 exhibits, with a new status conference set for July 22. The Norfolk County District Attorney's Office expressed intention to seek justice for O’Keefe through a retrial of the case.
