New York nanny arrested over murder of two young children The nanny, Yoselyn Ortega, was arrested over the deaths of 6-year-old Lucia Krim and her toddler brother Leo, who had been days shy of his second birthday. The children's mother, Marina Krim, found her son and older daughter stabbed to death in the bathtub as she returned home on Oct 25 from a swimming lesson with a third child, 3-year-old Nessie, who was unharmed, police have said. The nanny, who remains hospitalised and under guard, then began stabbing herself in front of the children's mother in the apartment on Manhattan's affluent Upper West Side. "No longer intubated and recuperating from what appeared to be wounds she inflicted on herself at the crime scene, Ortega agreed to talk to New York City detectives this afternoon," Deputy Police Commissioner Paul Browne said in a statement. After the interview, at 6:06pm today, Ortega was formally arrested and charged with murdering both children. He said that Ortega, 50, was charged with two counts of first degree murder and two counts of second degree murder over the killings, which sent shock waves through the city. Ortega, who had been employed by the Krim family for two years before the killings, lived with her son and sister near the Krims' apartment off Central Park and has been a naturalised U.S. citizen for a decade, police said.
