As the Oregonian reports:
“The man stepped into the kitchen and said he had just killed his wife. The officer saw the man was holding a butcher knife in his right hand.
"I was scared from the second he told me he killed his wife -- 'Oh, shit' is the only way to say it," Rios-Calderon said. "I know people are always like, 'Police officers aren't afraid,' but yeah, we're afraid. When he said that, I am like, 'This guy just killed his wife; what am I to him?'"
The officer took a step backward. The blood-soaked man moved closer to him. "It was like we were dancing," Rios-Calderon said.
