Unsolved Mystery 1 – Disappeared

You are in the parking lot at the shopping center and suddenly you hear a loud scream. You see a young woman being pulled into a car. The car drives off with squeaky tires. You remain shocked and still. Not much later a car with a young man arrives. He stops at the car and bag of the woman who has just been taken. You see his startled face and walk towards it. The man calls you and two other bystanders to him. He introduces himself as Marc and asks for your help. Of course you say yes, but whether you would have done that if you knew what kind of mystery you would end up in is still the question.
