(CBS/AP) NEW YORK - A memorial service for 6-year-old Lucia Krim and her 2-year-old brother, Leo, who were allegedly stabbed to death by their nanny last month, was held Monday in Manhattan at Avery Fisher Hall.
The Daily News reports that the children's grieving parents released a statement saying they wanted to celebrate their "beautiful lives" and not just mourn them.
Police say 50-year-old Yoselyn Ortega fatally stabbed the two kids in the children's Upper West Side apartment, before stabbing herself. Police charged Ortega, who is currently recovering from her wounds, with murder.
A third sibling was with their mother when the killings happened. Police say the mother returned home to discover her children dead and Ortega bleeding.
Ortega remains hospitalized under police guard.
