A woman told police she was overcome by "demons" when she smothered her 9-year-old son and then tried to kill herself by jumping in front of a subway.
Olivia Jean Noel was arrested Tuesday on murder and other charges in the death of Knil Jean Noel after telling police: "I did something terrible to my son."
She told detectives that "demons overtook her" when her son woke up Monday upset that a playmate hadn't come to his family's birthday dinner for him the night before, Police Commissioner Raymond Kelly said.

She told detectives she called the boy over to her bed and smothered him with a pillow, Kelly said.

The boy's father was at work at the time, police said. They said Jean Noel warned him during a telephone conversation: "You're going to have to forgive me."

Afterward, Noel said, she was overcome with remorse and threw herself in front of a train. She survived with a broken leg and severed fingers, police said.
