The New York City Fire Department (FDNY) is looking into a 4chan post purporting to be from a first responder detailing the death of accused sex trafficker Jeffrey Epstein more than 30 minutes before it was made public, according to BuzzFeed News.

A user on the message board, a popular hub for white supremacists and conspiracy theorists, reportedly wrote: “dont ask me how I know, but Epstein died an hour ago from hanging, cardiac arrest. Screencap this.”

The post came 38 minutes before ABC News broke the news of Epstein’s death at 8:54 a.m. on Saturday, according to BuzzFeed.

When other 4chan users were skeptical about the initial claims, the poster added further information, including the procedures used in the attempts to revive Epstein — details that have not yet been made public.

Deputy FDNY Commissioner Frank Gribbon said that while he “could not verify the accuracy” of the post, the fire department will review the matter. He added that any disclosure of medical information without consent would constitute a violation of privacy laws.
