Karen Read's second trial for allegedly running over her boyfriend with her SUV nears conclusion.

Karen Read's second murder trial is nearing its end. She is accused of hitting her boyfriend, Boston police officer John O'Keefe, with her SUV and leaving him to die in a snowstorm in January 2022. Defense experts, including biomechanic Dr. Andrew Rentschler and former medical examiner Dr. Elizabeth Laposata, testified that O'Keefe's injuries were inconsistent with being struck by a car and more likely due to a dog bite or beating. Read's defense argues that O'Keefe was the victim of a police conspiracy. She has chosen not to testify.
