Brody and Hooper are followed into the room by the medical examiner, who goes to the cold storage unit and retrieves a plastic bowl covered with a cloth. For some reason, despite the second attack on the boy and the story of the two fishermen's unsuccessful attempt to catch the shark, the authorities still seem to be sticking to their story of Chrissie Watkins being the victim of a boating accident. As Brody hands over the amended report he draws attention to the cause of death, which Hooper enunciates ('Probable boating accident') in a tone of disbelief. The chief averts his gaze and mutters a simple affirmative that essentially acknowledges his own culpability in the cover up. He moves to the window and tosses a wet oilskin jacket to the floor. It's an item of wardrobe that may have come from an earlier cut scene for its presence - like the towel the chief wears over his shoulder in two early scenes - is never explained. It does, however, provide a convenient visual metaphor that marks Brody's transition from a member of the group trying to cover up the threat to the one man who can make a difference. As he tosses the jacket onto the floor, he wipes his palms with a degree of distaste as if he is washing his hands of any previous involvement in the small town conspiracy.
The framing of Brody against the window recalls the earlier images of the chief in the town hall meeting. As if it were not enough to have his professional integrity questioned, he is chastised when he attempts to light up a cigarette. Hooper moves around to the other side of the table on which the remains have been set and lifts the severed arm into view. This no doubt is the same limb that Brody found on the beach and it will later be echoed by the shot of the estuary victim's leg spiralling to the sea bed. As Hooper lifts up the marbled arm, he utters the phrase 'This is what happens', which - like the insert shot itself - remains something of a non-sequitur in the scene.
Hooper's litany of potential causes of the girl's death ('It wasn't any propeller. It wasn't a coral reef. And it wasn't Jack the Ripper.') move from the plausible to the unlikely to the absurd. There is a shot of his profile as he bends down to bathe his face and when he turns to the camera, his final line ('It was a shark.') provides an aural match cut to the next scene, just as the close up of his face provides a visual one.
