A grand jury has charged an inmate with first-degree murder in the death last month of a Stillwater prison corrections officer.
Convicted murderer Edward M. Johnson, 42, who was already serving time for a previous slaying, had been charged on Aug. 2 with intentional second-degree murder and second-degree assault in connection with the attack on Joseph Gomm in a vocational building where offenders were offered welding classes.
He is now charged in Washington County District Court with first-degree premeditated murder and first-degree murder of a corrections officer. A first-degree murder conviction would keep Johnson in prison for life without the possibility of parole.
Johnson, who was moved to the more restrictive Oak Park Heights prison after the killing of Gomm on July 18, was scheduled to appear in court Friday.
The enhanced charges come in the same week that two others serving long sentences at Oak Park Heights were charged in Washington County with felonies in connection with violent attacks on corrections officers.
Gomm, 45, of Blaine, was bludgeoned with a hammer and stabbed, suffering substantial injuries to his head and face and two puncture wounds to his chest, according to the initial charges.
Johnson was to have been released from prison in late 2022 and then serve the balance of his sentence for a 2002 murder on supervised release. However, a conviction for Gomm's death could keep him behind bars for the rest of his life.
Johnson has a long history of violence that continued into his incarceration. At the time of Gomm's death, Johnson was serving a 29-year term for fatally stabbing his 22-year-old roommate, Brooke Thompson, while her 5-year-old daughter was nearby in their Bloomington home.
