MA v. Karen Read (2024) – Day 15 Trial Summary
Day 15 of the Commonwealth v. Karen Read trial centered entirely on the rigorous, highly contentious cross-examination of key prosecution witness Jennifer McCabe by defense attorney Alan Jackson. The defense focused on dismantling McCabe’s credibility, systematically challenging her timeline of the night John O’Keefe died, exposing inconsistencies between her current testimony and previous grand jury statements, and highlighting actions indicative of a coordinated cover-up. Specifically, the defense aggressively pressed McCabe on her communications with the Albert family, the potential deletion of phone logs, her presence at an unrecorded 42-minute meeting at an officer’s residence, and her eavesdropping on law enforcement’s interview with another witness, Kerry Roberts. McCabe consistently defended her actions, denying that she manufactured Read’s alleged “I hit him” confession, downplaying her close family ties to alternative suspects, and framing her constant updates to the Albert family group chat as a horrified reaction to Karen Read’s changing stories.

Summary Of Testimony
McCabe testified under a barrage of cross-examination regarding major timeline and behavioral discrepancies. She admitted to texting O’Keefe at 12:27 AM despite previously telling a grand jury she believed another witness’s vehicle was gone by 12:23 AM. While she denied seeing tire tracks or hearing a revving engine or collision, she firmly rejected the defense’s accusation that she manufactured the claim that Karen Read screamed “I hit him” three times.
When confronted with Cellebrite forensic records, McCabe denied intentionally deleting her phone logs but conceded there were specific historical entries she could no longer recall. She critically admitted to listening in on a private law enforcement interview of witness Kerry Roberts, and acknowledged updating the Albert family group chat in real time, stating she was “telling them everything.” Finally, she denied that a 45-minute visit to the home of officer Michael Lank was an “off-the-books” meeting, claiming she never actually spoke with Lank during that timeframe.
