"We are excited to help educators and leaders on the front lines of solving one of today's most pressing education challenges", Marc Sternberg, the foundation's K-12 education director and a former New York City education department official, said in a statement.
The young child was pronounced dead at St. Barnabas Hospital with injuries to the chest, and the other teen was transported to the hospital "in grave condition" with wounds in the arm and torso. Chief of Detectives Robert Boyce says a dispute among the three had been going on for about two weeks.
Mayor de Blasio and Schools Chancellor Carmen Farina were on hand to welcome students back into the troubled school less than 24 hours after the stabbing spattered blood across a fifth-floor classroom.
The suspect had been involved with an escalating "back-and-forth" with the victims for the past two weeks, Boyce said.
Police say Cedeno was taken into custody following Wednesday's attack at the Urban Assembly School for Wildlife Conservation in the Bronx.
In addition to murder, manslaughter, and attempted murder charges, Cedeno, who lives in The Bronx, also faces one count of attempted manslaughter, two counts of assault, and two counts of criminal possession of a weapon. Cedeno then took himself to the assistant principal's office, where police were called, and he was arrested.
The stabbing has left concerned parents shocked and wondering why metal detectors were not present in the schools.
"And less than half of students polled at the school previous year - 47 percent - said they felt safe on campus, well below the city average", the report says. A 16-year-old, who was also stabbed in the chest, allegedly with Cedeno's three-inch switchblade, remains hospitalized in stable condition.
Hornbeck said Cedeno often returned home in tears after enduring the bullying of McCree and the second stabbing victim Ariane Laboy, 16.
