The girl has yet to be identified but the babies name was Zuri Whitehead.
Trina Whitehead, her 31 year old mother told the New York Daily News that she is very close to the girl's mother and that she had insisted on taking the two month old for the night to give her some rest. Trina also has two other daughters ages 7 and 8 who she had let spend the night there previously and says she has never noticed any signs of strange behavior from the girl.
Reports say the mother, daughter and baby Zuri fell asleep on a couch in the downstairs area of their home. After the mother fell asleep the daughter took the baby upstairs and beat her to death. She came back down with the baby in distress about 45 minutes later and woke her mother. Zuri late died at the hospital from her multiple wounds including blunt impact injuries to the head, neck, body, arms and legs and liver lacerations.
The 11 year old was charged with murder on Monday.
