It's within the realm of possibility the initial poster simply "got lucky" by claiming to have specific knowledge when he or she did, less than an hour before news of Epstein's death became public.
Less than 40 minutes before ABC News first reported Epstein's death on Twitter, someone posted still-unverified details on 4chan, the anonymous message board popular with far-right trolls and white nationalists. The poster provided information on the resuscitation effort-writing, for instance, that the effort to revive Epstein lasted 60 minutes-leading to speculation the poster could be a first responder. "Screencap this", read the post, published at 8:16 a.m. Saturday. He added that the post has not been verified.
Oren Barzilay, the president of the union for EMT workers Local 2507 in NY, told Buzzfeed News, "Our members do not release this type of confidential information". He said the consequences for his members of releasing said information include "violations", "discipline", "suspensions", and "civil penalties".
The 4chan user reportedly made six posts about Epstein's death.
The report added that following the initial 4chan post, the anonymous user added more, detailed information in response to other users who responded to the initial post with doubt.
Dr. Keith Wesley, an emergency medicine physician, told Buzzfeed News that the 4chan post "sounds like standard American Heart Association guidelines, which most EMS agencies use".
"Telemetry implies the paramedics were in contact with a medical control hospital who then gave orders to give Sodium Bicarbonate, bicarb which is created to reverse the acid buildup in the blood from prolonged cardiac arrest", said Wesley, according to the report. "Hospital administrator was alerted, preparing statements". "Mr. Epstein was transported by EMS to a local hospital for treatment of life-threatening injuries, and subsequently pronounced dead by hospital staff".
There's also a chance, given how general some of the information was, that this 4chan post was just an act of serendipitous trolling, one that wasn't truly connected to Epstein in any way.
