Keri has to demonstrate the power of her hands, so she ties up Hannah on the chair and starts the game.
She puts her hands around Hannah's neck, strangling her different times. Then she keeps her quiet, handgagging her repeatedly. She pinches her nose too, to prevent her for breath. She puts a nylon bag over her head. Hannah can't breath under the bag. Keri makes the situation harder, putting a hand over her mouth. She keeps it for long time, until Hannah's death.
Keri plays the same game with Jamie. This time she wears a pair of black leather gloves. She strangles, handgags, handsmothers and finally puts the nylon bag over her head, suffocating her to death.
