What is the first name of the person who is stabbed to death?
Madison "Maddie" Young is a deaf-mute woman who temporarily lost her ability to hear and speak after a bout of bacterial meningitis at the age of 13 and lost both permanently after a corrective surgery gone wrong. She lives in a house, isolated in the woods with her cat. Her friend and neighbor Sarah visits her one day to return a copy of her book. In discussing Maddie's writing, she describes with excitement how her stories play out in her head like a film and she can see all the possible endings. That night, a masked killer chases Sarah to Maddie's house. A bloodied Sarah bangs on the door begging and shouting for help, but Maddie cannot hear her, and the man stabs her to death.
The man quickly learns of Maddie's infirmity and sneaks into the house through the main door, steals her phone, takes photos of her and sends them to her. Realizing this, she locks herself inside the house. The man cuts the power and sabotages her car. Maddie writes on the glass-paneled front door "won't tell, didn't see face, boyfriend coming home" with her lipstick. However, the man responds by taking off his mask and showing off his face. Maddie unsuccessfully tries to distract him with her car alarm to get Sarah's phone from her body, but she manages to stab his arm with a hammer's claw. He mocks Maddie, revealing he has the phone as well. He takes one of Sarah's earrings out and puts it in his pocket.
