Police charge New York City nanny in stabbing death of kids NEW YORK - New York City police say they've charged a nanny with murder in the stabbing deaths of two children last month. Police finally could interview 50-year-old Yoselyn Ortega as she continues to recover from self-inflicted stab wounds. They charged her in her hospital bed Saturday night with two counts each of first- and second-degree murder. Police say Ortega fatally stabbed 6-year-old Lucia Krim and her 1-year-old brother, Leo, on Oct. 25 in the children's Upper West Side apartment. She then stabbed herself. A third sibling was with their mother when the killings happened. The mother returned home to discover her children dead and Ortega bleeding. Ortega remains hospitalized under police guard.
