Nanny alleged to have murdered two children in New York
Mother 'psychotic' after finding boy, two, and girl, six, stabbed to death in bathtub and the help with throat slashed on Upper West Side

A New York mother returned home to her luxury apartment to find two of her children, a 2-year-old boy and a 6-year-old girl, fatally stabbed in a bathtub by the family's nanny, the authorities said.
The nanny herself lay gravely injured on the floor, near a bloody knife, with an apparently self-inflicted slash to her own throat.
The gruesome crime sent shockwaves through the wealthy enclave of the Upper West Side, where nannies are often an integral part of privileged children's lives.
Police Commissioner Raymond Kelly said the mother, Marina Krim, had left her flat a block from Central Park to take one of her other children, a three-year-old girl named Nessie, to a swimming lesson on Thursday afternoon. The two other children, Leo and Lucia, were left with the nanny, Yoselyn Ortega, 50.
