Yoselyn Ortega was hospitalized for weeks with stab wounds police said were self-inflicted after the Oct. 25 killings. She was arraigned at the hospital in November but has since been released. She appeared in court Friday wearing glasses and her hair in braids.

Lawyers say psychiatric evaluations for Ortega are not complete, and they need more time to review medical records to determine whether she is fit for trial.

Authorities say Ortega stabbed 6-year-old Lucia Krim and her 2-year-old brother, Leo, while the children's mother was out with a third child.

The three were found in the bathroom of the Upper West Side apartment.
