DEDHAM, Mass. (NewsNation) — Jury deliberations in the Karen Read murder trial continued Monday as jurors struggle to reach a verdict.
Just as they did Friday, jurors Monday told the judge that they remained deadlocked and at an impasse. The judge, just as she did Friday, instructed the jury to keep deliberating and invoked the “Tuey-Rodriguez instruction,” essentially a final push to the jury.
If the jury is still hung after that, the judge could declare a mistrial.
In the event of a mistrial, the prosecution could retry Read in the future. When a retrial could occur remains unknown, but experts told CBS News that it could be several months or even more than a year before a retrial against Read.

Read, a 44-year-old Massachusetts professor, faces second-degree murder and other charges in the 2022 death of her police officer boyfriend, John O’Keefe.
O’Keefe, a 16-year veteran of the Boston Police Department, was found unresponsive in a snowbank outside of a fellow officer’s home in Canton, Massachusetts in January 2022. He was rushed to the hospital where he was later pronounced dead.
Prosecutors claim Read hit him with her SUV outside of the home during a snowstorm after a night of drinking. The couple was going to the other officer’s house to hang out with friends, but witnesses testified that neither made it there.
Defense attorneys, though, say Read is the innocent victim of a police cover-up. O’Keefe, Read’s lawyers say, was killed during a fight at the house and dumped on the front lawn.
If Read is convicted, she could face life in prison with the possibility of parole.

What first might have seemed to be an open-and-shut case has drawn outsized attention, fueled by true-crime fanatics, conspiracy theorists and Read’s pink-shirted supporters.
The case has divided the Canton community — the Boston suburb where O’Keefe was raising his niece and nephew after their parents’ deaths and where many of the witnesses and even investigators know one another.
Several Read supporters gathered outside the courthouse during the eight-week trial. On Friday, about 100 of them were waiting as the jury deliberated.
