The mother of a teen who was fatally stabbed inside of a Bronx school spoke publicly Thursday about a lawsuit filed against the NYPD, the Department of Education and her son's alleged killer.

Louna Dennis, the mother of slain 15-year-old Matthew McCree, spoke outside her attorney's office in Brooklyn.

Officials say McCree was fatally stabbed by Abel Cedeno at the Urban Assembly School for Wildlife Conservation on Sept. 27, 2017.

Dennis’ attorney, Sanford Rubenstein, says the school had noticed Cedeno was bringing a weapon to school prior to the stabbing and no metal detectors were requested by the principal.

Rubenstein's comments come after a lawsuit filed by McCree's mother against the New York City's Department of Education. 

Cedeno is scheduled to stand trial for charges including manslaughter, assault and criminal possession of a weapon. However, the teen claims he carried out the stabbing because he was bullied by McCree and another student for his sexuality.

Many who knew McCree, including teachers and students, have reportedly disputed the claim.

The killing marked the first death in a New York City school in decades.

In December, 2017 the DOE announced it would close 14 public schools, including the Urban Assembly School for Wildlife Conservation.

News 12 reached out to the DOE and the NYPD for comment and was referred to the city’s law department, which handles such cases. A spokesperson there told News 12 that "this was a tragic incident. The safety of students and staff is a top priority. We cannot comment further while this case is pending."
