A nursing home patient wielding a hand saw slashed a fellow resident, cut a worker and scraped a police officer Tuesday in a rampage that ended when he was subdued with a stun gun, authorities said.
David J. Cooper, 53, of Petaluma was jailed on charges of assault with a deadly weapon and assault on a police officer at Sunrise Assisted Living after seriously injuring a woman who lived there.
Officers found the woman in the lobby with head wounds when they arrived at about 1:30 a.m. Cooper was nearby with a wood-handled tree-trimming hand saw, said Petaluma police Sgt. Matthew Stapleton.
As police closed in on Cooper, he threw a wheelchair down a stairwell at them and tossed his saw at an officer. Police fired bean bags and used a Taser to subdue him.
Cooper and an employee injured in the struggle were treated for minor injuries.
