DEDHAM, Mass. (WJAR) — The Karen Read murder trial continued for a second week of testimony on Monday.
The Massachusetts woman is accused of killing Boston Police Officer John O'Keefe's -- who was her boyfriend -- during a blizzard in 2022.
O'Keefe's family was emotional in Norfolk Superior Court as the 911 call from the morning he died was played for jurors.
"How long has he been out there?," A dispatcher asked.
"I don't know. I don't know," Jennifer McCabe responded.
Screaming could be heard in the background of the call, which was difficult to understand at some points.
Read is facing a list of charges, including second degree murder. She's accused of backing into O'Keefe with her SUV.
Lt. Paul Gallagher, of the Canton Police Department, took the stand. He said frozen blood, as well as a cocktail glass, were found in the snow during the investigation.
Gallagher spent more than two hours on the stand, sharing how he secured the crime scene more than two years ago and how he used a leaf blower to find evidence.
"You can see it exposing the cocktail glass," he said, of the leaf blower. He also described it as "a unique scene" and added that he had never processed a scene in the snow before.
Gallagher told prosecutors police used six red cups to collect samples of frozen blood.
"We didn't think swabbing was going to be easy to do if it was frozen," Gallagher said.
The defense asked what else police uncovered that morning.
"How many pieces of taillight did you find on or around that property?" David Yannetti asked.
"That morning, none, " Sgt. Sean Goode of the Canton Police Department said.
Read's attorneys, who allege a cover up, also questioned why inside the home wasn't searched thoroughly that morning.
"Nobody put John O'Keefe anywhere but where he was found, and that included his girlfriend," Gallagher said.
Last week, members of the jury toured the property O'Keefe's body was found.
A black Lexus appearing to be Read's was parked near the house. It was missing taillight and had some scratches on the right-side.
Norfolk County Assistant District Attorney Adam Lally told the panel in court to look at the vehicle carefully.
"Specifically, I'm going to ask you to take note of sort of the center console and the front driver's compartment of that vehicle," Lally said.
The defense added it was an opportunity to gain perspective.
"You have heard about a flagpole, a fire hydrant, a house. We're going to ask you to take special note of where those are in relation to other things physically at the scene," defense attorney Alan Jackson said.
Jurors are allowed to use what they saw in deliberations down the road to reach a verdict.
The jury also previously heard from Canton firefighters who took Read from the scene to the hospital. They said she was worried about caring for O’Keefe's niece and nephew.
"She was asking if he was dead. 'Could he be dead? Could he be dead?' And she said, 'Could I have hit him?'" Jason Becker, a Canton firefighter, testified. "She had said they had gotten into an argument, that she was sad because that was the last thing she had said to him."
