It’s like a billboard for disillusionment and mistrust, and it’s everywhere: “Epstein didn’t kill himself.” The phrase has been slapped on beer cans, printed on sweatshirts, blurted as a nonsequitur in cable news interviews, scrawled on posters held up at Southern college football games and on San Francisco bar bathroom walls cramped with Sharpied phone numbers and profanity. It's popped up on classical music subreddits, where it was determined that the phrase is in 7/8 time. It’s been not-so-secretly spelled out in the impeachment-related tweets of Representative Paul Gosar. (You may remember him as the guy who couldn’t get an endorsement from his own siblings while running for office. This week, he’s the guy whose last 23 posts are a paranoid acrostic.) It’s become a joke on dating apps, and it’s been an incessant talking point for social media users left, right, and slantways.

See, despite its popularity among staunch Trump supporters like Gosar, the “Epstein didn’t kill himself” meme, while political, isn’t actually partisan.

Millionaire sex offender Jeffrey Epstein died in jail in August while waiting to be tried for trafficking minors. Epstein had been facing allegations of sex trafficking and sexual abuse of dozens of girls, some as young as 14, for over a decade. In 2008 he served 13 months in jail after pleading guilty to soliciting sex from a minor. He consorted with many powerful men, including presidents Trump and Clinton, and his likely conviction was poised to be the #MeToo movement’s biggest public victory since Harvey Weinstein or Larry Nassar. Then, while the guards outside his door slept, he suffered fatal injuries to his neck that New York City’s chief medical examiner, Barbara Sampson, ruled suicide.

As soon as news of Epstein’s death broke, people were suspicious. Trump suggested Epstein was killed for having dirt on Clinton. New York City mayor Bill DiBlasio and Democratic representative Al Green expressed doubts as well. The equal-but-opposite #TrumpBodyCount and #ClintonBodyCount both trended on Twitter. “Even mainstream journalists were teasing that he had been murdered, teasing the conspiracy,” says Joseph Uscinski, a political scientist at the University of Miami and author of American Conspiracy Theories. Sampson’s ruling quieted most, but Fox News reignited the theorizing after airing an interview with forensic pathologist Michael Baden, who alleged that Epstein’s death was a homicide. For many on social media, including alpha-bro podcaster Joe Rogan, the fact that Baden was being paid by the Epstein family didn’t matter. “Epstein didn’t kill himself” became a meme, helped along by another Fox News segment in which a former Navy SEAL closed out an interview about military dogs with the phrase, apropos of nothing.

Nobody’s saying Epstein’s death isn’t weird. In fact, it’s because it’s so weird that it's become a widespread meme in the way other Trump-era conspiracy theories (like Pizzagate) have not. According to a Rasmussen poll, less than a third of Americans believe that Epstein committed suicide. True information vacuums, events that happen without witnesses, invite conspiracy theorizing. Recall Malaysian Airlines flight 370, which disappeared without a trace due to, depending on which kind of truther you ask, the Russians, a black hole, or a portal to another dimension. Often, the theory is niche, predicated on a particular worldview: When Supreme Court justice Antonin Scalia died of natural causes in 2016, some speculated that Barack Obama (or Star Trek actor Leonard Nimoy) had him killed for political gain. The Epstein conspiracy theory is different, though. “It’s one of those theories where all you really have to agree on is that Epstein was murdered,” Uscinski says.
