“He believed me, and he dropped the knife.”

McKinnis said he grabbed the man, identified as Steven Rivera, 28, and detained him until Oklahoma City police arrived.

I was thinking that I was going to have to go hand-to-hand with this guy. Law enforcement training and experience paid off, and the bluff worked,” McKinnis said.

The woman who fled the scene, identified as Nelson, drove to a nearby convenience store, police said. She died at a hospital.

Allen Galbreath, 47, the man McKinnis witnessed being stabbed, also was taken to a hospital. He is expected to survive, police report.

Rivera was booked into Oklahoma County jail on complaints of murder and assault with a deadly weapon, police said.

“I should have had my weapon. I normally do. We’re told to always have your weapon with you whether you’re on duty or off duty because you never know what’s going to happen,” McKinnis said. “I was just fortunate enough to be there and be able to act and take the bad guy into custody.

“Ironically, I was able to do it without handcuffs or a gun or anything else.” has disabled the comments for this article.
