That written report seems to conflict a bit with the local televised news report and conference. The way I heard it, The victims were in the car, the perp pointed a gun at the victim/driver/wife’s face, and then the passenger/victim took his gun out and shot him. The police were interviewed and said the victims did get their money.
"Wait a moment honey... this man has a gun in my face..."
BANG
"Okay. I'm done. Now how much money do we want to withdraw...?"
