Paediatrician Marina Krim returned to her family's apartment near Central Park with her three-year-old daughter on Thursday (local time) after her two other children and their nanny failed to show up as planned at a local dance studio, Police Commissioner Ray Kelly said.
However, when she arrived home it appeared the nanny, YoSelyn Ortega, and the children, a boy aged two and his sister aged six, were not in the apartment either.
Commissioner Kelly said Ms Krim saw that the apartment was dark and returned to the lobby to ask the doorman if the nanny and kids had gone out.
The doorman said no, and she returned to the apartment, he said.
"The apartment is dark, she goes into the bathroom, (and) that's where she discovered the bodies," Commissioner Kelly said.
