A Massachusetts jury found Karen Read not guilty of murdering her Boston police officer boyfriend in 2022, nearly a year after her first prosecution ended in a mistrial.

She was acquitted of the most serious charges, including second-degree murder, manslaughter and leaving the scene after an accident resulting in death.

The jury did find her guilty of operating under the influence of liquor. The judge immediately sentenced her to one-year probation, the standard for a first-time offense.

Cheers could be heard from outside the courthouse, where supporters of Read have gathered, while the verdict was being read. Read embraced her legal team and cried following the verdict.

The jury began deliberating the afternoon of June 13 in Norfolk County before reaching a verdict Wednesday afternoon.

Prosecutors alleged Read hit her boyfriend, John O’Keefe, with her car outside the Canton home of fellow police officer Brian Albert after a night of heavy drinking in January 2022 and then left him to die there during a major blizzard.

The defense had argued that Read’s vehicle did not hit O’Keefe and instead said O’Keefe was attacked by a dog and beaten by other people who were in the house before he was thrown out in the snow to die.

Read pleaded not guilty to the charges and has maintained her innocence.

In brief remarks upon leaving the courthouse, she thanked her “amazing supporters” for their financial and emotional support for the past nearly four years.

“No one has fought harder for justice than John O’Keefe than I have — than I have and my team,” Read added.

Following the verdict, several of the witnesses who testified against Read called the result of the retrial “a devastating miscarriage of justice.”

“Today, our hearts are with John and the entire O’Keefe family. They have suffered through so much and deserved better from our justice system,” members of the Albert and McCabe families said in a statement. “While we may have more to say in the future, today we mourn with John’s family and lament the cruel reality that this prosecution was infected by lies and conspiracy theories spread by Karen Read, her defense team, and some in the media.”

During deliberations, the jury asked four questions, including, “If we find not guilty on two charges but can’t agree on one charge, is it a hung jury on all three charges or just one charge?” the judge told attorneys in court.

The judge told the jury she is not able to respond to their question, telling attorneys it was a “theoretical question.”

The jury also asked about the time frame for when Read is accused of driving under the influence, whether video clips from Read’s interviews about the case are to be considered as evidence and if she is convicted on a sub-charge, if that would mean she is guilty on the overall charge.
