Police provided this photo of the runner, later identified as Rynn Berry, after he collapsed in Prospect Park Dec. 31.
A runner without identification on him who collapsed in Prospect Park on New Year's Eve and remained unidentified and unconscious for a week in a hospital has died.
Rynn Berry died Thursday at New York Methodist Hospital.
The 68-year-old man was taken to the hospital in critical condition on Dec. 31. He was not carrying any identification.
His half brother, Charles Berry, identified him this week after seeing a photograph on social media of a man in a hospital bed with various tubes attached to him. The New York Times says he confirmed the death.
Rynn Berry was a respected figure in the vegetarian and vegan movements.
He self-published a book titled "Vegan Guide to New York City." He also wrote several other books on the history of vegans and vegetarians.
