Visible crew/equipment: Watch the scene where Frank gets killed. In the last shot of this scene, we see a soldier standing over the dead body. Keep an eye on the right side of the screen as the camera slowly moves away and you should see one of the cameras and a cameraman on the ground next to a large metal object.
Answer: Jim's parents did not get infected with Rage. They decided to commit suicide, hence the pills and alcohol beside the bed. They basically decided that it was better to die than become infected, hence the message on the back of the picture. Those that are infected with Rage, the length of time it takes to die probably relates to how they were infected. If they were infected through the mouth or something similar then they would live for a while, if they were infected through a serious wound then obviously they would become infected but would not live as long because of the serious injury.
