You heard the scream of a boy and tried to see through your window who it was. You saw a group of people forcefully dragging a boy into a car before driving away with the boy. You acted smartly and followed the car and reached an abandoned house. The kidnappers took the boy inside the house and left. They will probably come back after some time. This is the best chance you will get to rescue the boy from the custody of the kidnappers. Do not expect the rescue mission to be an easy one but that does not mean that it is an impossible mission.
