Nearly 40 minutes before the first news report on disgraced financier Jeffrey Epstein's death, someone had posted unverified details of it on 4chan, the message board popular with white nationalists, BuzzFeed News is reporting.

"Dont ask me how I know, but Epstein died an hour ago from hanging, cardiac arrest. Screencap this," read the post, published at 8:16 a.m. ET on Saturday.

BuzzFeed News said the first official report on Epstein's death came in a tweet at 8:54 a.m. from Aaron Katersky, an ABC News correspondent.

The 4chan poster later added more details about Epstein's death, including the procedures allegedly used to resuscitate him.

A spokesperson for the New York City Fire Department said the information did not come from FDNY.

Dr. Keith Wesley, an emergency medicine physician, reviewed the 4chan post at BuzzFeed News' request and said it noted standard procedures for paramedics.

"This sounds like standard American Heart Association guidelines, which most EMS agencies use," Wesley said.

BuzzFeed News noted it is not clear who posted the news of Epstein's death on 4chan, but first responders and hospital workers would have access to information laid out in the post.
