The cop who called Karen Read a “wack job c–t” in texts to his buddies has been fired from the Massachusetts State Police, The Post has learned.

Trooper Michael Proctor — the former lead investigator in Read’s alleged murder of her cop boyfriend John O’Keefe — was canned from his job officially after his admittedly “unprofessional” messages were revealed at her trial last year.

Proctor’s family claimed the 12-year veteran trooper had been “wrongfully” terminated and defamed. It was not immediately clear if Proctor planned to bring legal action.

“Proctor and his detectives led a meticulous and thorough investigation of integrity, and despite today’s wrongful termination, and great harm and defamation this case has inflicted on him and his family, Proctor still believes justice will be served,” the family said in a statement.

During Read’s first trial, Proctor was forced to answer for his embarrassing correspondence about his investigative target, Read.

Proctor joked about searching for nudes of Read on her phone and made fun of her Crohn’s disease, saying, “She’s got a leaky balloon knot. Leaks poo.”

He also seemed to have made up his mind about Read’s guilt when he texted: “I looked at [O’Keefe’s] body in the hospital. He was banged up. She hit him with her car.”

Proctor also called her “re—-ed” and said he “truly” hated her lawyer, calling the attorney an “a—hole.”

The cop admitted from the witness stand that the messages were “regrettable” and “something I’m not proud of.”

What to know about the Karen Read murder case

• Karen Read, 44, was charged with second-degree murder for allegedly mowing down her boyfriend, Boston Police Officer John O’Keefe, as she was dropping him off to meet friends in Canton, Mass., on Jan. 29, 2022.
• The night of O’Keefe’s death, the couple had been out on a bar crawl, with Read allegedly consuming seven drinks in just 90 minutes, according to reports.
• Prosecutors claim that after Read drunkenly ran over her boyfriend, she drove off and left O’Keefe to die outside as a snowstorm was set to sweep in.
• Read’s lawyers argued she was framed in a sweeping law enforcement cover-up and that O’Keefe actually died after getting into an altercation with his officer friends.
• On July 1, 2024, Judge Beverly Cannone declared a mistrial in the case since the jury was not able to reach a unanimous verdict after five days of deliberations.
• On April 22, 2025, Read will stand trial for the second time, facing the same charges despite her lawyers’ failed plea attempt to the top Mass. court to drop the murder and hit-and-run charges.
• Read faced up to life in prison if she had been convicted on the top count of murder.

Proctor was suspended without pay the week after Read’s case ended in a mistrial in July because of a deadlocked jury.

His family has insisted that the messages show he’s only “human” in that they were on his personal phone to friends and family, and a forgivable response to a beloved fellow cop’s murder.

Read faces a retrial on April 1 in the case accusing her of running O’Keefe over with her SUV after a night of drinking, and leaving him for dead in a snowbank in Canton, Massachusetts, as a snowstorm was coming in.

Read has maintained her innocence and claimed she is the scapegoat in a sweeping law enforcement cover-up.

A federal probe, which may have been looking into possible law enforcement misconduct, closed earlier this month without charges.
