The shooting Wednesday at Miami Valley Hospital in Dayton happened before a gunman carrying a rifle and a handgun killed four people and himself at a medical building on a hospital campus in Tulsa, Oklahoma.
Dayton police said inmate Brian Booth, 30, was receiving treatment when he struggled with Darrell Holderman, 78, and took his gun.
Holderman worked for a company hired by the Montgomery County Sheriff’s Office to provide security for inmates who are admitted to hospitals. He sustained multiple skull fractures and lacerations to his hands during the struggle, police said.
After Booth fatally shot Holderman, people ducked for cover as he pointed the gun at them while running down a hallway and into the parking lot, where he killed himself, police said.
Booth was being held in the county jail on a probation violation stemming from a 2015 burglary, authorities said.
