NEW YORK (AP) — A New York City nanny who killed two small children in her care is facing life in prison.

Yoselyn Ortega (YOH'-sih-lihn ohr-TAY'-guh) is set to be sentenced Monday following her conviction of murder last month in the 2012 deaths of Lucia and Leo Krim.

The nanny's lawyer had argued that Ortega was mentally ill and couldn't be held responsible for the children's deaths.

Lucia was 6. Leo was 2.

Prosecutors say Ortega knew what she was doing and understood "every stab, every slash" as she slaughtered the children.

The children's mother found them in a bathroom. The parents' testimony made jurors weep during the emotional trial.
