Massachusetts State Police Col. Geoffrey Noble said that in the aftermath of the Karen Read case, the department will continue to work on improvements in oversight and accountability.

Prosecutors alleged Read hit her boyfriend, John O'Keefe, with her car outside another officer's home in January 2022 and then left him to die there during a blizzard.

A jury cleared Ms. Read of charges related to the 2022 death of John O’Keefe, a Boston police officer, and convicted her only of drunken driving, in a trial that attracted wide attention.
