A mentally retarded 11 year old girl has killed her two younger brothers and then also tried to kill herself because the devil told her to do it.
Fernanda Cruz, who is suspected of being schizophrenic, suffocated her three-month-old brother and days later smothered her three-year-old sibling with a pillow.
But police did not realize she was the killer until weeks later when she took pills in an attempt to overdose and ended up in hospital, where she confessed to what she had done.
