Read, 45, of Mansfield, was acquitted last month of second-degree murder and manslaughter in the January 2022 death of O’Keefe, her Boston police officer boyfriend.
Prosecutors alleged Read hit O’Keefe with her SUV, leaving him to die in a blizzard on the front lawn of fellow officer Brian Albert’s home at 34 Fairview Road in Canton following a night of drinking. Her lawyers painted a picture of police misconduct and theorized that O’Keefe was killed by colleagues, followed by a vast cover-up.
Read was convicted of drunken driving, however, for which she will face a year’s probation.
The 22-page lawsuit was filed on behalf of O’Keefe’s brother Paul, his father, John O’Keefe II, his mother, Margaret O’Keefe, and his niece and nephew, whom he was raising at his Canton home after both of their parents died.

Karen Read opening statements begin

The lawsuit alleges that Read “outrageously created a false narrative” and the O’Keefe family has suffered “emotional injuries, severe physical pain, anguish, emotional distress and other harm… caused by defendant Read’s negligence.”
“In the months, weeks, and days leading up to January 29, 2022, JJ (John) and defendant Read’s relationship was deteriorating. During such time, defendant Read picked fights, experienced jealousy, and had delusions of unfaithfulness,” the lawsuit claims.
Damon Seligson, Charles Waters, and Aaron D. Rosenberg, all with the Boston-based firm Sheehan Phinney, joined Read’s defense team last week to represent her in the lawsuit, MassLive reported. They join lawyers, including William Keville Jr., who have already represented her in the civil case.
The lawsuit also names C.F. McCarthy’s and Waterfall Bar & Grill as defendants, the two bars on Washington Street in Canton where O’Keefe and Read were seen drinking hours before his death.

The suit does not state the dollar amount the family is seeking. Instead, it demands, “…costs, compensatory and punitive damages, lost value of next of kin and any other relief this Court deems appropriate.”
