Teen who jumped to death from Vessel was laughing with sister before leap, guard says

The 14-year-old boy who leaped to his death in front of his horrified family at the Vessel in Hudson Yards was laughing and running with his sister right before, according to a worker who witnessed the tragedy.

“There were lots of tourists around. The kid was racing up the stairs with his younger sister and having a blast, having so much fun,’’ said a security guard at the Manhattan tourist attraction to The Post on Friday, a day after fatal jump. “One of my colleagues told them, ‘I know it’s fun and stuff, but you are not allowed to run in the Vessel,’ and, ‘Stay with your parents.’ Somehow, when he got to Level Eight, he jumped,” the guard said of the teen from upscale Livingston, New Jersey.
