An accomplished writer who first found success as a teenager, Ned Vizzini, has died at 32. The chief medical examiner’s office of New York confirmed Friday that Vizzini committed suicide on Thursday, according to the Associated Press.

His brother, Daniel Vizzini, said that the author jumped off the roof of their parent’s apartment building in Brooklyn. The medical examiner’s office confirmed Vizzini’s blunt impact injuries are consistent with a fall.

The writer’s most notable work, “It’s Kind of a Funny Story,” is set mostly in a psychiatric ward and follows a 15-year-old protagonist who botches a suicide attempt. The novel, published in 2006, was later adapted into a feature film starring Zach Galifianakis. Another novel, “Be More Chill,” chronicled a teenager who gains confidence after swallowing a tiny supercomputer. Humorous approaches to dark themes characterize his prose.

At 15, Vizzini’s amusing essays about high school life began appearing in the alternative weekly, New York Press. This exposure led to writing work for New York Times Magazine and a collection of essays published when he was only 19.

Born April 4, 1981 in Manhattan as Edison Price Vizzini, the writer later legally changed his first name to his nickname, Ned, according to the New York Times. He leaves behind his wife, Sabra Embury, and their son, Felix.

Chris Columbus, who had been working with Vizzini on a fantasy book series told the Los Angeles Times on Friday that “he was the perfect collaborator, with a brilliant imagination and a sharp sense of humor. I’ve spent nearly every day over the past two years working closely with him, and I can’t fathom a world without him.”
