The 2-year-old son and 6-year-old daughter of a CNBC executive were found dead by their mother in a dry bathtub in the family's Upper West Side apartment Thursday night. The nanny suspected of stabbing the children was in critical condition Friday with apparently self-inflicted injuries. (ASSOCIATED PRESS / John Minchillo)
