Things to know about the retrial of Karen Read in the killing of her police officer boyfriend

2025-05-22 05:43 Last Updated At:05:51

A brain surgeon testified at Karen Read’s second murder trial Wednesday that the victim's skull was most likely fractured when he fell backward and hit his head.

Read, 45, is accused of backing her SUV into her boyfriend, Boston Police Officer John O’Keefe, 46, and leaving him to die on a snowy night in the front yard of another officer’s home after she dropped him off at a party there in January 2022. Her lawyers say she was framed in a police conspiracy and that someone inside the home that night killed him.

A mistrial was declared last year. Read’s second trial on charges of second-degree murder, manslaughter and leaving the scene has so far appeared to follow similar contours to the first.

Dr. Aizik Wolf, director of the Miami Neuroscience Center, testified about reviewing photos of O'Keefe and his autopsy report. He described a “classic blunt trauma injury" and said he believes O'Keefe struck his head on the ground.

“My opinion is that's what caused this whole injury,” Wolf said. “The only way he could get this kind of an injury was to fall backward, hit the back of his head."

Asked by prosecutor Hank Brennan whether the injuries were consistent with being attacked with a bat or other object, Wolf said no, because O'Keefe had a “nondepressed skull fracture.”

Wolf said O'Keefe likely lost consciousness quickly but did not die immediately.

Christina Hanley, a state police crime lab analyst, also testified Wednesday. She described examining a broken drinking glass and pieces of glass and plastic found near O'Keefe's body, bits of plastic recovered from his clothing, pieces of glass found on the bumper of Read's SUV and the vehicle's broken taillight.

Several pieces of glass found on the ground matched the drinking glass, she said, and red and clear plastic found on O'Keefe's clothing was consistent with the taillight.

Wednesday's testimony was delayed for about two hours after Judge Beverly Cannone said an issue had come up that required her to speak to each juror individually. She did not explain the issue, but after speaking to jurors, reminded them of the importance of not discussing the case with anyone or allowing anyone to try to discuss it with them.

On the witness stand for a second day Tuesday, digital forensics analyst Shanon Burgess was questioned by Read's attorney about “trigger” events recorded by her Lexus SUV, including a three-point turn and backing up.

“None of the information in that black box ... indicates there was a collision on January 29?” asked attorney Robert Alessi.

“Not by itself,” Burgess answered.

“Are Lexus SUVs trigger-happy?” Alessi asked.

“I do not know, sir,” Burgess said.

Yet Burgess used the word “collision” in a report he wrote about the data, Alessi noted. Burgess said that information came from State Police reports, prompting Alessi to accuse him of confirmation bias.

Burgess, who specializes in analysis of digital forensics from vehicles and cellphones, works for Aperture LLC, an accident reconstruction, biomechanics and digital forensics company. He didn’t participate in the initial investigation of Read’s car in 2023.

BEIJING (AP) — Canada, breaking with the U.S., has agreed to cut its 100% tariff on Chinese electric cars in return for lower tariffs on Canadian farm products, Prime Minister Mark Carney said Friday.

Carney made the announcement after two days of meetings with Chinese leaders. He said there would be an initial cap of 49,000 vehicles on Chinese EV exports to Canada.

China will reduce its tariff on canola seeds, a major Canadian export, to from about 84% to about 15%, he told reporters.

THIS IS A BREAKING NEWS UPDATE. AP’s earlier story follows below.

BEIJING (AP) — Faced with new global challenges, the leaders of China and Canada pledged Friday to improve relations between their two nations after years of acrimony.

Xi Jinping told visiting Prime Minister Mark Carney that he is willing to continue working to improve ties, noting that talks have been underway on restoring and restarting cooperation since the two held an initial meeting in October on the sidelines of a regional economic conference in South Korea.

“It has been a historic and productive two days,” Carney said, delivering a statement to journalists outside a Beijing park Friday afternoon. “We have to understand the differences between Canada and other countries, and focus our efforts to work together where we’re aligned."

“It can be said that our meeting last year opened a new chapter in turning China–Canada relations toward improvement,” China's top leader said.

Carney, the first Canadian prime minister to visit China in eight years, said better relations would help improve a global governance system that he described as “under great strain.”

He called for a new relationship “adapted to new global realities” and cooperation in agriculture, energy and finance.

Those new realities reflect in large part the so-called America-first approach of U.S. President Donald Trump. The tariffs he has imposed have hit both the Canadian and Chinese economies. Carney, who has met with several leading Chinese companies in Beijing, said ahead of his trip that his government is focused on building an economy less reliant on the U.S. at what he called “a time of global trade disruption.”

A Canadian business owner in China called Carney's visit game-changing, saying it re-establishes dialogue, respect and a framework between the two nations.

“These three things we didn’t have,” said Jacob Cooke, the CEO of WPIC Marketing + Technologies, which helps exporters navigate the Chinese market. “The parties were not talking for years.”

No announcement was made on tariffs between China and Canada, which is a sticking point in the relationship.

Canada followed the U.S. in putting tariffs of 100% on EVs from China and 25% on steel and aluminum under former Prime Minister Justin Trudeau, Carney’s predecessor.

China responded by imposing duties of 100% on Canadian canola oil and meal and 25% on pork and seafood. It added a 75.8% tariff on canola seeds last August. Collectively, the import taxes effectively closed the Chinese market to Canadian canola, an industry group has said. Overall, China's imports from Canada fell 10.4% last year to $41.7 billion, according to Chinese trade data.

China is hoping Trump’s pressure tactics on allies such as Canada will drive them to pursue a foreign policy that is less aligned with the United States. The U.S. president has suggested Canada could become America's 51st state.

Carney departs China on Saturday and visits Qatar on Sunday before attending the annual gathering of the World Economic Forum in Switzerland next week. He will meet business leaders and investors in Qatar to promote trade and investment, his office said.
