.............is dead after two-story fall The Nets super fan who was carried out of Madison Square Garden by security guards after allegedly waving his prosthetic leg around died Sunday after jumping out a second-story window in Queens, sources said. Jeffrey Vanchiro — who was ejected from the Dec. 2 Knicks-Nets game — plunged from the window of his father’s home in Flushing on Saturday night, according to the sources. “He won’t be recovering from this,” his fiancée, Kristi Evans, told The Post at New York Hospital Queens only hours before he died. “He’s at the end of his life, and this is the time when his friends and family are coming to say goodbye.” She later said goodbye to him on social media. .................. Vanchiro, 38, who also went by the name Jeffrey Gamblero, was upset about the way he was portrayed in the media after he was thrown out of the Garden, according to Evans. “Regarding the fall, all I can say is that he has been dealing with the stress and trauma of what happened at Madison Square Garden,” she said. “It’s been tough for him since then,” Evans added. “He wasn’t a crazy fan hitting people with his prosthetic leg. That was a lie. He’s a good man.” Vanchiro either jumped through the glass pane or forced it out before jumping out, the sources said. He landed on a concrete stairwell in the back yard.
