The Karen Read Murder Trial: Canton Confidential NBC10 Boston

Cross-examination of Michael Proctor, who led the investigation into John O'Keefe's death wrapped up on Wednesday, but not before Proctor admitted to using derogatory and sexist language to describe Read in text messages.

We have heard from more than 50 witnesses since the murder trial against Karen Read began, but Massachusetts State Police Trooper Michael Proctor's testimony Monday has a lot of people talking.

Massachusetts State Police Trooper Michael Proctor, who led the investigation into the death of John O'Keefe, faced questions about his handling of the case and scrutiny over comments he made, via text message, about Read and her defense team.

The sixth week of the highly-publicized Karen Read murder trial has come to an end, with many prosecution witnesses remaining before the defense presents its case.

A high-ranking Massachusetts State Police trooper returned to the stand Thursday in the Karen Read murder trial, taking questions from the defense about Karen Read's damaged taillights, how many drinks she had the night John O'Keefe died, and if a security camera video of Read's SUV after it was seized by police had been edited.

Today we heard more testimony about Karen Read’s tail light. Plus, surveillance video concerning the number of drinks she may have had before driving, and testimony from a key state police investigator who worked on the case.
