A medical examiner testified that she could identify the cause of John O’Keefe’s death as being due to a head injury and hypothermia. However, she could not ascertain whether the manner of death was homicide, accidental, or occurred in another way. This testimony was presented on Thursday during the murder trial of Karen Read concerning the 2022 death of O’Keefe, a 46-year-old Boston police officer.
Dr. Irini Scordi-Bello, a forensic pathologist with the Massachusetts’ Office of the Chief Medical Examiner, conducted the autopsy on O’Keefe on January 31, 2022.
While Scordi-Bello determined that O’Keefe’s death was caused by head trauma and hypothermia, the manner in which he sustained these injuries remained unclear.
The blunt impact to his head was the primary cause of death, she testified, but hypothermia contributed. He had a deep cut and bruising to the back of his head. Once she looked at it from the inside, she found multiple skull fractures and brain bleeding. And his body temperature when he arrived at the hospital was 80.1 degrees compared to a normal body temperature of 98.6.
After Judge Beverly Cannone sent jurors home for the day, Alessi argued that new disclosures about expert testimony from Aperture, which conducted reports for the prosecution, would put the “entire defense” at risk if allowed this late in the game.
The disclosure was dated May 8 but was received by the defense May 11, he said.

“I don’t like to use hyperbolic words, but the word has been used against us — ambush, ambush, ambush,” Alessi said. “If there’s ever an example of an ambush, this is it.”
In a heated back and forth, Brennan described the disclosure as evidence of a significant variance between the internal clocks in Read’s Lexus SUV and John O’Keefe’s cellphone data.
Cannone did not announce a decision before adjourning court for the day.
Read is due back Friday at 9 a.m.
She could face life in prison if convicted of the most serious charge.
