Read’s defense attorneys argued that O’Keefe, who allegedly had a long-standing disagreement with someone at the party, was severely injured during an argument at the party and may have been attacked by a dog given the deep wounds on his arm.

A jury on Wednesday acquitted Read, 45, on the most serious charges in her second trial of leaving John O’Keefe to die in a snowstorm after hitting him with her car outside a suburban Boston house party more than three years ago. She was also acquitted of leaving the scene of an accident causing death.

Prosecutors allege 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.
