Mayor Bill de Blasio and Schools Chancellor Carmen Fariña are hearing from parent leaders in the wake of a fatal stabbing at a public school in the Bronx Wednesday. Many questions at a forum in Harlem Monday focused on school safety, fear of violence in schools, and the need for additional resources, like mental health services.

Last Wednesday, police say 18-year-old Abed Cedeno fatally stabbed a 16-year-old student at the Urban Assembly for Wildlife Conservation in the Bronx. Cedeno said he had been bullied. The incident remains under investigation.

Ranesha Westbrooks said she's shocked by what happened.

"It's horrifying to know that a child has actually died in a school, I'm just, like, out of my mind right now," she said.

Mayor de Blasio said the city wants to make sure an incident like this never happens again, and has made recent investments in restorative justice, mental health services, and teacher training. He said the purpose of the forum was to hear from parents about where additional improvements can be made so the city can do even more.

"Everyone's feeling this moment in common," de Blasio said. "Everyone wants to figure out what we can do better."

Fariña said school safety officers now have additional training, and noted that the city has hired dozens more social workers and guidance counselors to provide mental health and other services.

"I think in many cultures, it is considered a stigma, and we have to get over that," she said. "If you have problems, keeping them to yourself is not going to solve them. It's going to be about talking to each other that makes a solution."

Speaking after the meeting, Zakiyah Ansari, with the Alliance for Quality Education, said she'd like to see more forums for students to talk about their thoughts and feelings.

"Not just about bullying, but overall, like what can we do better in our schools to make you feel safe? And not just in the sense of your body being harmed, but mentally and emotionally as well," she said.
