Former Massachusetts State Trooper Michael Proctor, who was fired last month for his role in the Karen Read investigation, is on the witness list for her second trial, court documents revealed Monday.

Jurors were seen shaking their heads during Proctor’s testimony at her first trial, which ended with a hung jury. In a series of text messages that were read in court, he called Read a “wack job,” a “babe… with no a–” and a “c—.” He added that he wished she would kill herself and joked about looking through her phone for nude selfies.

He was the lead investigator into the death of Boston Police Officer John O’Keefe, Read’s boyfriend at the time of his death, in January 2022.

An autopsy found the cause of his death to be blunt force trauma to the head and hypothermia.

O’Keefe had skull fractures, brain bleeding, swollen black eyes and cuts to his right arm, but the forensic pathologist held off on calling it a homicide, leaving the manner of death undetermined.
