(NEW YORK) -- A mother returning to her luxury New York apartment with her 3-year-old found her other two children stabbed to death in a bathtub and the kids' nanny lying unconscious nearby with apparently self-inflicted wounds, New York Police Commissioner Ray Kelly told reporters.
The mother and daughter were returning from a swimming lesson to the luxury La Rochelle apartment building on the city's affluent Upper West Side at approximately 5:30 p.m., Kelly said. When they found the apartment dark, they asked the doorman if the nanny had left with the other children only to be told that was not the case.
"She goes looking for her children and finds her 6-year-old daughter and 2-year-old son stabbed to death in the tub," Kelly said.
The mother's screams could be heard emanating from the apartment, Kelly said.
The nanny, approximately 50 years old, was in critical but stable condition at St. Luke's Hospital, he said.
She was in police custody, officials said earlier.
According to Kelly, the preliminary police investigation had not yet yielded a possible motive for the deaths.
Officials were not yet identifying the victims or the nanny, Kelly said.
