Three high-level witnesses in the Karen Read murder trial have uttered “I wish” on the stand as they tried to prove there’s no backing to a claim by the defense that they’re part of a frame job.

The witnesses – Brian Albert, Matthew McCabe and Jennifer McCabe – testified they “wish” they had seen John O’Keefe enter 34 Fairview Road in Canton in the early hours of Jan. 29, 2022, or his body laying on the property’s front lawn that cold, snowy morning.

Defense Attorney Alan Jackson took exception to Jennifer McCabe saying “I wish I had” during Day 15 of testimony in the trial at Norfolk County Superior Court in Dedham.

“Sounds like that’s a little rehearsed,” Jackson told McCabe last Tuesday. “Not at all,” McCabe responded.

McCabe is a principal figure in the conspiracy the defense alleges the Albert and McCabe families are involved in with local and state police to frame Read for the murder of O’Keefe.

McCabe’s Google search for “ho[w] long to die in cold,” at 2:27 that morning., the defense contends, “decisively implicates” McCabe and her brother-in-law Brian Albert in O’Keefe’s murder. Albert owned 34 Fairview Road at the time with his wife, Nicole.

McCabe has testified that she made the search only as Read instructed her to do so after the two women and Kerry Roberts found O’Keefe’s bloody body covered in snow, a little after 6 a.m.

Jackson asked whether McCabe saw O’Keefe’s body earlier that morning when she and others who gathered at the home for an after party and celebratory drink for Brian Albert Jr.’s 23rd birthday noticed Read’s SUV parked out front and periodically moving forward.

“I never saw a body,” McCabe said to which Jackson responded with a “Thank you.”

“I wish I had,” McCabe added. “Sounds like that’s a little rehearsed,” Jackson followed.

Just days earlier, McCabe’s husband Matthew McCabe testified he didn’t notice O’Keefe sitting in Read’s SUV when he looked out the window nor a “6-foot-2 man lying on the front lawn.” He added that he didn’t see or hear anything suspicious come from outside.

“And once again, you didn’t see a 6-foot-2 man lying on the front lawn, correct?” Defense Attorney David Yannetti asked.

“No,” McCabe replied. “I wish I did, but I didn’t.”

Read, 44, of Mansfield, faces charges of second-degree murder, motor vehicle manslaughter and leaving the scene of a collision causing the death of O’Keefe, a 16-year Boston Police officer when he died at age 46.

Prosecutors say that after a night out drinking the pair argued and she killed him by backing her Lexus SUV into him at high speed, leaving him to die in the cold during a major snowstorm.

The defense has developed a third-party killer theory and has alleged a massive frame-up job to ensnare their client.

Brian Albert, one of the three people identified and a retired Boston Police sergeant, has testified that “John never came into my house that night.”

“He, and the defendant,” Albert said with a glance to Read,  “would have been welcome with open arms if they did. I wish they had.”
