There are some self-inflicted wounds by investigators in the case," says a former federal prosecutor who watched opening statements on Tuesday for Karen Read's retrial.

The prosecution and defense offered vastly different facts and theories as Karen Read's second murder trial got underway Tuesday.

Karen Read pleaded not guilty to murder charges in the death of Boston police officer John O’Keefe and is facing a retrial after a jury was unable to reach a verdict last year.

Karen Read's second murder trial began Tuesday with new faces at the prosecutor's table but the same central defense claim as her first trial: she didn't kill her Boston police officer boyfriend in 2022.
