Disgraced Massachusetts State Police Trooper Michael Proctor, who rose to infamy over his handling of the Karen Read murder case, has been fired, the agency announced Wednesday.

State Police Col. Geoffrey Noble terminated Proctor at the recommendation of a trial board, which found him guilty of unsatisfactory performance and consuming alcohol while on duty. Noble’s personnel order specifically points to Proctor’s conduct as lead investigator on Read’s case, particularly the vulgar texts he sent to family, friends, and coworkers about the defendant.

“My decision to terminate Mr. Proctor follows a thorough, fair, and impartial process,” Noble said in a statement. “I have weighed the nature of the offenses, their impact on our investigative integrity, and the importance of safeguarding the reputations of our dedicated women and men in the State Police. This decision reflects our unwavering commitment to upholding our values, enhancing public trust and ensuring the highest standards of service and accountability.”
