From the NY Post:
A three-year-old boy died this evening after he was thrown from a seventh floor terrace in Queens by a "very depressed" woman living in his family’s apartment, authorities said.
The toddler, whose name was withheld, died in New York Hospital of Queens shortly after the horrific attack on Leavitt Street in Flushing at 8:35 p.m.
Queens DA Richard Brown identified the suspect as Xiao Aiu Cai.
The 53-year-old woman then tried to commit suicide by jumping from the same terrace but was pulled back by others in the apartment, Brown said.
Cai, who had just gotten into a dispute with her daughter, was taken into custody and charges were pending, Brown said.
"She’s a very depressed individual and is on medication," Brown said.
Cai is not related to the child, whose fourth birthday is on Nov. 12.
The dead child’s mother was in the apartment at the time.
