DEDHAM, Mass. — The defense in Karen Read’s murder retrial rested its case on Wednesday afternoon, the 31st day of testimony, after jurors heard from the final witness in the murder case.
Read, 45, of Mansfield, is accused of striking John O’Keefe, her Boston police officer boyfriend, with her Lexus SUV and leaving him to die alone in a blizzard outside of a house party in Canton at the home of fellow officer Brian Albert on Jan. 29, 2022, following a night of drinking.
Read’s lawyers allege O’Keefe, 46, was beaten, bitten by a dog, then left outside a home in Canton in a conspiracy orchestrated by the police that included planting evidence against Read.
The defense in Karen Read’s murder retrial rested its case on Wednesday afternoon, after Andrew Rentschler, a biomechanical engineer and accident reconstructionist from ARCCA, faced questioning all day, including a heated cross-examination.
The jury was dismissed for the day at 3:38 p.m.
The prosecution has decided not to call rebuttal witnesses before closing arguments commence. On Thursday, the defense and prosecution will return to court without jurors for a charge conference at approximately 10:00 AM. Closing arguments are scheduled for Friday morning. The jury will then be sent off to deliberate Read’s fate.
Hank Brennan continues to challenge Dr. Rentschler's conclusions and Dr. Rentschler continues to push back:
HB: You have no information about the angle of Mr. O'Keefe's body at the time. The defendant's Lexus was traveling backwards on January 29th, 2022. Do you?
Brennan asking Dr. Rentschler about his contact with the defense and coming to testify in 1st trial
HB: When you had conversations with the defense, did they offer to give you transportation assistance getting here? AR: They provided a ride to and from the airport. Yes. HB:…
At least one prosecution witness previously said there were no x-rays of JOK taken to look for things like broken bones. X-rays were taken and AJ is asking Dr. Rentschler about that:
AJ: Would it be appropriate to come to any opinions... if you were to ignore, X-rays, if they…
“If you fell back on grass, you would tend to see, you might see grass in the wound, or you would tend to see an irregular kind of crisscross pattern of the flattened grass,” Laposata said.
Doctor says O’Keefe’s wounds consistent with animal attack
Dr. Loposata said the wounds on O’Keefe’s arm were consistent with an animal attack. Judge Beverly Cannone prohibited the defense from asking if it could have been a dog.
Loposata also testified that hypothermia did not contribute to O’Keefe’s death despite. The medical examiner’s report said O’Keefe died from hypothermia and blunt impact injuries to the head.
Elizabeth Laposata testifies regarding John O'Keefe's injuries
“The body did not have any hypothermia,” Laposata said.
Laposata also said she didn’t think eye injuries suffered by O’Keefe were consistent with being hit by the rear of Read’s SUV. She said there was no evidence of impact from a vehicle at all.
Judge Beverly Cannone told the jury on Tuesday that deliberations will begin no later than Monday, with the prosecution getting a chance to call rebuttal witnesses before closing arguments.
Read has pleaded not guilty to charges of second-degree murder, manslaughter while operating under the influence, and leaving the scene of a crash resulting in death.
