Can anyone list the deaths?

Do you mean just the teenagers, or the members of the community? Three characters are alive at the end (Ava, Liam, and Candy). The teenagers are decapitated in various ways: Seth is the first to go. His head is cut off by a car trunk. Tiffany, the next victim, is knocked down by the Horseman, and falls into a bear trap which cuts off her head. Doc is next; he is pinned to a wall and decapitated with an axe. Nash's head is cut while he's driving a car. The HH leaps and decapitates Nash in mid-air. Lizzie, the last to die, gets it the worst. She's dragged by the HH into an attic, and in view of Ava, Liam, and Candy, has a spike slowly driven through her head, which eventually penetrates her head and comes out her eye socket, She is then decapitated. All the deaths are quick, with the exception of Lizzie, who dies a slow and painful death, not to mention what they do to her head after it's cut off.
