Funeral of 11-year-old Brooklyn boy who died while subway surfing – Grandma blames school

Shocked relatives and friends gathered Friday for the funeral of a sweet 11-year-old boy who died while subway surfing – while his grandmother blamed the school for the tragic death.

Cayden Thompson secretly left Fort Greene Preparatory Academy Monday morning before beginning his fatal ride on a G train, his paternal grandmother, Angela Thompson, told The Post exclusively outside the funeral.

“How could he just walk out of school?” she said. “I don't understand. How can a baby sneak out of school? They just let him go.”

There was a palpable sense of sadness on the street outside Cayden Thompson's funeral at a Lower East Side morgue.

A woman moaned and nearly collapsed as the boy's white casket was carried into a hearse. An aunt, who asked not to be identified, described Thompson as fearless, charismatic and “very sweet.”

Cayden was sitting on the roof of a G train entering the Fourth Avenue-Ninth Street station around 10:15 a.m. when his head struck a beam, officials said.

Angela Thompson remembered her grandson as a sweet child with a witty sense of humor who never failed to say “thank you.”

She said Cayden loves skateboarding, cycling, scootering and has recently become very interested in soccer.

The grieving grandmother called it “absolutely crazy.” Cayden, a sixth-grader, was able to walk out of school Monday morning.

“You saw him at breakfast, but he's not going to first class,” she said. “What's that like?

“Then how come you don't contact anyone? He must have left school at 9:30, 10, and no one found out what happened to him until after 1 p.m. What's up with that?”

Officials from the city's education department said the incident was under investigation.

“My heart breaks for the family, friends and loved ones of this little child who was taken from us far too soon,” Chancellor of the Exchequer David Banks said in a statement.

“Subway surfing is a dangerous epidemic in our city and the risk is never worth it. I ask all members of our community to check on the young people in their lives and remind them to always ride indoors. We will be providing additional support to this school in the coming days and weeks.”
