Deaths [SPOILERS!]
If you were as confused as I was about who was whom and who died where, this should help you out:
NANCY (camp counselor) - tied to an anchor and thrown overboard
ASHLEY (curly-haired girl who got in the car accident) - trips while running from Richard, then gets shot with the rifle
CLAIRE (chubby quiet girl) - hooked on some contraption and dragged into the water
MADISON (blonde girl who offered the other girls food) - steps on a bear trap, later falls to her death (if she wasn't already) with Remi
DAWN (Nancy's aide) - shot by Richard with the rifle after being separated from the other girls
REMI (curly-haired girl who took charge after Nancy's death) - fell to her death after Mickey cut the rope holding her and Madison
JUSTINE (brown-haired girl with the camera who mocked Holly at the beginning) - killed by Mickey with a machete
HOLLY (blonde girl with asthma) - drowned by Richard after splitting from the other girls
NATALIE (blondish girl who told Richard and Mickey to keep it down) - shot by Richard while looking for the keys to the boat
RICHARD (killer) - throat slit by Mickey
