The prosecutors in the retrial of Karen Read want to keep out the testimony of a digital forensics expert who alleged that a friend of John O’Keefe’s searched “hos long to die in cold” on Google. Read’s first trial in the death of her Boston police officer boyfriend O’Keefe ended in a mistrial on July 1.

Prosecutors say an expert hired by Karen Read's defense team should not be allowed to testify about hotly contested Google searches during her second trial.

Prosecutors argue in a motion that Richard Green's testimony is not based on fact and would only confuse the jury in Karen Read's retrial.
