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.
