Story highlights Victim's mom: "He was probably frightened for his life"

Deadly shooting was followed by protests in Tulsa

(CNN) A mental health call turned into a deadly shooting in Oklahoma when three law enforcement officers confronted a knife-wielding man outside a convenience store, the Tulsa County Sheriff's Office said.

Two deputies and one Tulsa police officer opened fire and shot 29-year-old Joshua Barre on Friday morning. He was taken to a hospital, where he later died, the sheriff's office said.
