Amityville Death House is a 2015 American horror film directed by Mark Polonia, written by John Oak Dalton, and starring Eric Roberts.
As Tiffany and her friends tend to Florence and read the diary, they are spied on by Abigail, who has begun slaughtering the descendants of the villagers who killed her in the 17th century.
After murdering five of the other descendants, Abigail snaps Florence's neck, and mesmerizes Aric and Dig into attacking Bree and Tiffany.
During the struggle, Tiffany's blouse is ripped open to reveal that she has six breasts, a sign that she is a witch, according to the Dark Lord.
Tiffany, having discerned that Abigail's power is tied to her diary, sets the book on fire; this causes Florence's house to explode, which attracts the attention of the passing Sheriff McGrath.
