A Memphis teen charged with fatally stabbing his high school principal two years ago is scheduled to make a court appearance.

The lawyer for 18-year-old Eduardo Marmolejo said last month that he's optimistic the case against his client will be resolved at a hearing Tuesday.

Marmolejo was 16 when he was charged with first degree murder in the August 2011 stabbing of 49-year-old Suzette York, his principal at Memphis Junior Academy. A juvenile court judge decided in September 2011 that Marmolejo's case should be moved to adult court. The teen has pleaded not guilty.

Investigators say Marmolejo planned the killing for months. York's body was found in a pool of blood in a classroom.

Defense lawyer Leslie Ballin and prosecutors have been discussing a plea deal.
