What would you do?

Its snowing you are headed to a quick trip to the ATM there's no one else on the street. And then suddenly a man steps out from the shadows with a gun he asks, for your phone, your purse/wallet all the cash that you have on you. And your coat. You dont hesitate you give it all up. You're standing there freezing. He grabs your items from you turns and darts across the street and is hit by a car. He goes flying into the air. Your phone, coat, and wallet hits the ground. The car speeds off as it leaves the guy bloody on the pavement. What do you do next?
