SANTA CLARA — A police officer responding to a stabbing report early Wednesday broke through the front door of a home and immediately encountered a man overpowering his roommate and raising a knife for a potential killing strike, prompting the officer to fatally shoot the man, authorities said.

Santa Clara Police Chief Cory Morgan detailed the deadly shooting at a news conference Friday, lauding Officer Robert Allsup’s quick actions in a rapidly unfolding clash.

“The officer’s split-second decision in a life-threatening situation ensured that nobody else was injured or killed,” Morgan said. “Our officers train for moments like this, not because we want to face them, but because we must be prepared to protect lives when every second counts.”
