The whole incident seems improbable, but the end result is entirely predictable.
With police forces across the country under increased scrutiny over killings of unarmed black men, Phoenix police said in a statement that its officer called for backup, and then saw Brisbon appear to remove something from the car's back seat.
It said the officer, a seven-year veteran of the department, gave him several commands to show his hands, before Brisbon "placed one or both hands in his waistband area" and then fled.
The officer chased and caught up with him, it said, and during a struggle the policeman believed he felt the handle of a gun while holding the individual's hand in his pocket.
"The officer gave the suspect several commands to get on the ground but he refused to comply, yelling profanities at the officer," said the police statement issued on Wednesday.
At that point a resident opened an apartment door and both men stumbled into her home, it said, adding that the officer was unable to keep a grip on the suspect's hand.
"Fearing Brisbon had a gun in his pocket the officer fired two rounds striking Brisbon in the torso," it said.
The police department said the back-up officers arrived after the shooting, and while they and members of the fire department treated Brisbon, he was pronounced dead at the scene.
