DUMONT, N.J. (PIX11)-- A 10-year-old boy jumped to his death out of a 2nd-floor classroom window at the Grant School in Dumont, New Jersey on Friday. A law enforcement source confirmed to PIX 11 that his leap was intentional. The boy later died at Hackensack University Hospital from his injuries.

"I went to that school," said a man who lives directly next to the school."Nothing has ever happened like this before here, ever. I've lived here my whole life. Dumont's a quiet town. We've never had anything like this happen. It's a tragedy."

Weekend activities appeared to still be underway at the school on Saturday. The parking lot was busy with parents and children, coming and going. 422 students, ranging from kindergarteners to 5th grade, attend the school.

An eyewitness to the tragedy said that after the boy landed on the pavement below, he was still moving. The eyewitness was outside his home shoveling snow when it happened around noon on Friday. He also said he saw a woman looking down from the open classroom window.

Another neighbor, who is a teacher in another district, says the children were eating lunch in the classroom when it happened. She said the teacher was not in the room, but that an aide was.

The tragedy reportedly happened after a chess game ended badly, and the boy wrote a note to another student. Ambulances came rushing to the school around 12:30 p.m. on Friday. In addition to transporting the boy to HUMC, an ambulance was called for an upset witness.

On Twitter yesterday, "Dumont Class of 2017" posted a message calling for all Dumont High School students to wear "either blue or purple on Monday to support Vladimir and his family."

Police did not release the child's family name as of Saturday afternoon.

Messages by "Dumont Class of 2017" go on to say that wearing blue in the boy's memory will represent anti-bullying, and wearing purple is to promote suicide awareness.
