After Sheriff Brody discovers the remains of Chrissie on the beach, he types up his official police report. A closeup of said report indicates he took the victim's remains to the "Corners Office." Yikes!
I'm gonna give Brody the benefit of the doubt here and say he was probably just rattled from finding the remains of a violent shark attack. And not that he's a moron who doesn't know how to spell "coroner."
