His close friend, Martin Rowe, posted to Facebook Thursday:
“I’ve been to the hospital, and I’m sorry to confirm that Rynn Berry passed away today at 12:30 p.m. His family was with him. I can give no further details, since I am not a next-of-kin, but I was told that he had gone into cardiac arrest in Prospect Park. When I saw him yesterday, he seemed peaceful.”
Berry was a well-known vegan author. He had been running in the Park on NYE without any identification when he collapsed. The author was often seen at the farmer's market in Union Square.
