Steinke came up the stairs, staggering and covered in blood, and screamed at her to kill her brother, she said. "He yells at me 'Stab him, just stab him! Slit his throat!'" she said. "I said, 'I can't, I can't,' and he said, 'You have to. I did this for you.'"
Weeping as she spoke, the accused said the little boy pleaded with her, saying: "I'm scared. I'm too young to die."

She said they had sex again in a friend's apartment after the killings, only hours before her family's bodies were discovered by her brother's friend.

Very very disturbing.

edit: she's 13 actually. typo.
