The new prosecutor in the Karen Read case appears to have been quite excited by a television special aired last year in which the accused murderer’s family was interviewed — and thinks it may bear even more fruit.

Special prosecutor Hank Brennan on Friday requested two pieces of material he says could be beneficial in his prosecution of the Mansfield woman accused of striking her boyfriend, Boston Police Officer John O’Keefe, with her car and leaving him to die in the cold on Jan. 29, 2022.

The motions stem from an Aug. 7, 2023, Boston 25 News segment in which Read’s father William Read, her mother Janet Read, and her brother Nathan Read were interviewed by reporter Ted Daniel.

Read, 44, of Mansfield, was charged in Norfolk Superior Court on June 9, 2022, with second-degree murder, motor vehicle manslaughter and leaving the scene of a collision causing death.

The first is a motion to compel Verizon to hand over all the phone records of Read’s father for the day of O’Keefe’s death to the next day, and the call detail records of the period of Dec. 30, 2021, to Jan. 30, 2022.

The second is to compel the keeper of records at WFXT-TV, known as Boston 25, to turn over the entire video of the interviews for information not contained in the five-minute and 40-second news segment.

“Through the evening and morning of the victim’s death, the defendant made numerous calls to various people providing varying and sometimes conflicting statements about the whereabouts of the victim,” Brennan writes in the Verizon motion. “The defendant’s phone call records identify calls to both William Read and Janet Read and texting between William Read and Karen Read.”

Brennan says that he intends to call William Read to the stand in Karen Read’s second trial scheduled for January. William Read was a fixture in the courtroom during his daughter’s first trial, which ended with a hung jury, earlier this year along with his wife and son.

“His phone records must be made available to use as potential impeachment evidence depending on the testimony,” Brennan writes. He adds that, “A review of William Read’s media statements, statements and conduct at court hearings, and other public engagements relative to this case, show that William Read is hostile to the Commonwealth regarding his daughter.”

He adds elsewhere that he’s requesting the data-rich smaller time-frame request with the call detail records for the longer period “to compare the timing and frequency of Karen Read’s calls to her father on the night of the victim’s death as compared to the frequency, or lack thereof, on dates not involving this alleged crime.”

“The records are reasonably likely to establish a pattern or common occurrence between the defendant … regularly calling her parents in the middle of the night after consuming large quantities of alcohol and engaging in a domestic dispute with her boyfriend,” Brennan wrote.

This is a developing story.
