Susan said she just looked at Sharon straight in the eye and said, "Look, bitch, I don't care about you. I don't care if you're going to have a baby. You had better be ready. You're going to die and I don't feel anything about it...In a few minutes I killed her."
Susan said she saw that there was Sharon's blood on her hand and she tasted it. "Wow, what a trip! To taste death, and yet give life."
