Dr. Daniel Wolfe, a crash reconstructionist, testified that the damage to Read's vehicle contradicts the prosecution's claims regarding the nature of the impact that led to O'Keefe's death.

However, prosecutors have raised concerns about Wolfe's credibility, noting that the defense paid his firm for testimony without informing the court.

Special prosecutor Hank Brennan challenged Wolfe's methods, questioning the size of the crash test dummy used and the limited number of tests conducted.

The prosecution also scrutinized the testimony of Loughran, suggesting he may have been influenced by an online blogger supporting Read's innocence, raising questions about the integrity of his statements.

The defense's strategy is focused on creating reasonable doubt rather than proving Read's innocence, as emphasized by defense attorney Mark Bederow.

Jury instructions indicate that Read may not testify, citing her Fifth Amendment rights, as her lawyers advise against it due to her previous public statements.

The outcome of this trial could have significant implications for law enforcement accountability and the treatment of high-profile defendants within the judicial system.

The defense argues that the investigation into O'Keefe's death was flawed, citing deceit, incompetence, and bias in the handling of the case.

As the trial progresses, further developments are anticipated, particularly with expert testimonies continuing to play a pivotal role.

Court proceedings were recently interrupted due to excessive heat, affecting the jurors' ability to hear testimony, showcasing the ongoing challenges faced during the trial.

Karen Read is currently undergoing her second murder trial for the death of her former boyfriend, Boston Police Officer John O'Keefe, who died in January 2022 after allegedly being struck by Read's SUV during a blizzard.

The trial, which began on May 7, 2025, is nearing its conclusion, with the defense expected to wrap up its case soon.
