The judge in the Abel Cedeno fatal school stabbing case heard arguments Tuesday on whether to allow a 90-minute police interview with the 20-year-old as evidence.

Abel Cedeno is accused of fatally stabbing 15-year-old Matthew McRee and injuring another student, Ariane Laboy, during a fight inside a classroom at the Urban Assembly School for Wildlife Conservation in September 2017.

He was charged with manslaughter and assault and would have to serve sentences, if convicted on those charges, separately.  He could face up to 50 years in prison.

At issue is the admissibility of a confession Cedeno made in the video.

Cedeno and his family didn't talk to reporters after Tuesday's hearing. He and his lawyers maintain that Cedeno, for years, was the victim of school bullying.

McRee's mother says she’s happy the case is moving forward and wants the justice that her son “truly deserves.”

The trial is expected to begin on June 27.
