Nanny 'stabbed children to death'
A nanny at a luxury New York City apartment building is believed to have stabbed two small children to death before turning the knife on herself.
The children's mother returned to her Upper West Side home to find them dead in the bath and their nanny, with what police say were self-inflicted stab wounds, lying nearby.
The nanny, who was found near a knife, was taken to hospital in a critical condition and is in police custody. Authorities said she is suspected of killing the children.
The children's father, CNBC digital media executive Kevin Krim, who had been away on a business trip, was met by police at the airport on his return and given an escort to the hospital.
Music therapist Rima Starr, who lives on the same floor as the family, said she heard screams coming from their apartment at around 5.30pm.
"There was some kind of screaming about, 'You slit her throat!"' she said. "It was horrible."
The children's mother, Marina Krim, entered the dark apartment with her three-year-old and initially thought that her other two children were out with the 50-year-old nanny, police commissioner Raymond Kelly said.
She went downstairs and asked the doorman whether he had seen them leave.
When he said no, she went back upstairs and discovered her one-year-old son Leo and her six-year-old daughter Lucia, known as Lulu, in the bathroom.
It was unclear how many times the children had been stabbed.
Ms Starr believed the nanny had been hired recently. "I met her in the elevator, the day before yesterday, and was making small talk," she said.
