At the first sign of trouble, corrections officer Joe Parise sprinted across the sprawling Oak Park Heights prison to rescue a colleague under attack.
Parise helped restrain the inmate, then returned to his station. Less than 10 minutes later, he collapsed amid a fatal medical emergency.
"You don't go to work to die," Tim Henderson of AFSCME Council 5 said Tuesday, somberly marking the union's second on-duty death of a corrections officer in just two months.
Monday's tragedy and an overall surge in violence at Minnesota state prisons have spurred union members to demand harsher punishments for inmates who assault staff members.
At a news conference, Henderson decried widespread officer shortages across the state and unprecedented low morale among personnel. He cast much of the blame on the Republican-controlled Legislature for failing to hold hearings on the matter despite repeated pleas for increased staffing.
Last year, the Minnesota Department of Corrections (DOC) said it requested state funding for 187 additional corrections officer positions to bolster security in its facilities.
"Unfortunately, the Legislature approved only 15 of those positions," said DOC spokeswoman Sarah Fitzgerald, adding that the agency is committed to "doing everything possible to improve safety" for its workers.
Henderson promised to introduce another robust staffing bill this session, which union officials hope will be approved. "We don't expect any legislative game playing or politics to be involved in that," he said. "This shouldn't be a partisan issue."
