Jurors in Karen Read’s second murder trial ended their first full day of deliberations Monday without a verdict in the case over whether the Massachusetts woman killed her Boston police officer boyfriend.

Judge Beverly Cannone sent jurors home for the evening, telling them to come back refreshed Tuesday at 9 a.m.

The 12-person panel began discussing Read’s fate Friday, June 13, for about two hours, after lawyers finished delivering closing arguments in the eight-week-long murder retrial. By 4:25 p.m. on Monday, after more than nine hours of deliberations, they still had not reached a decision.

Read, 45, has pleaded not guilty on three charges, including second-degree murder, vehicular manslaughter while intoxicated and leaving the scene of a collision resulting in death.

Prosecutors accuse Read of backing into John O’Keefe with her Lexus SUV after a night out drinking in January 2022. Her defense team has suggested she was framed for the crime by sloppy and biased investigators.
