Sinn Sage breaks into Keri's apartment. She is wearing a black balaclava and a pair of black leather gloves. She reaches the bedroom, where Keri is sleeping. She suffocates Keri in three different ways.
First time, she puts a pillow over her face and repeatedly holds her breath, pressing it tightly.
Second time, she puts a nylon bag over her head and covers her mouth with gloved hands, to be sure she can't breath anyway.
Third time, she handsmothers her, covering her mouth with a gloved hand and pinching her nose with other.
In each case, Sinn smothers Keri until she dies.
