According to the Star Tribune, a relative identified the inmate, as Department of Corrections officials declined to name the inmate, as Edward Muhammad Johnson, who is serving a nearly 29-year sentence for second-degree murder. After the assault, he was transferred to Oak Park Heights, the state’s only Level 5 maximum-security prison.

In a news conference, Roy said a weapon was used to kill the 45-year-old officer from Blaine. The Star Tribune is reporting that Gomm was stabbed before being bludgeoned with a hammer.

Johnson, 42, was convicted in 2003 of stabbing his roommate, 22-year-old paralegal Brooke Thompson, to death while her 5-year-old daughter was nearby.

More than 1,600 inmates are housed at the 104-year-old prison, 527 of them sentenced for homicide.
