A 2-year-old and a 6-year-old were reportedly stabbed to death by their nanny on New York's Upper West Side. Their mother, Marina Krim, returned home from taking her 3-year-old to swimming practice to find her children murdered in a bathtub. Krim found their nanny, 50-year-old Yoselyn Ortega, in the kitchen lying next to a bloody knife and bleeding from her throat. police believe the injury was self-inflicted.

Ortega is in critical condition at New York Presbyterian, where both children were pronounced dead. Authorities have no motive for the crime, but say that the Krim family was very close with Ortega. Mrs. Krim kept a blog that documented her adventures with her children, and it showed the family taking a trip to the Dominican Republic to visit Ortega's family.
