Social media pages that appear linked to Cesar Altieri Sayoc displayed evidence of emotional turmoil and political anger before he was arrested on Friday and identified as the suspect behind at least 12 mail bombs sent to leading Democrats, prominent activists and members of the media.

There are multiple Facebook accounts, a LinkedIn account and a Twitter page that appear to belong to Sayoc. They show his name and display many photos that strongly resemble the man who was taken into custody by the FBI on Friday. The postings appear to be from an ardent supporter of President Trump, one who despised many Democrats.

The person identifying himself as Sayoc described himself as an entrepreneur, or, as he put it on LinkedIn, a “Promoter, booking agent Live entertainment, owner, choreographer.” In multiple pictures on Facebook, the person identifying as Sayoc can be seen wearing a pro-Trump “Make America Great Again” hat and attending Trump campaign rallies. In the months leading to Trump’s election in 2016, the Facebook pages regularly promoted articles containing bizarre conspiracy theories about Democrats — including allegations that Trump’s rival, Hillary Clinton, sold weapons to the jihadist group ISIS, claims that Democrats were “buying votes” and rumors of an imminent Muslim terrorist attack.

Based on the Facebook posts, the person identifying as Sayoc was fixated on the idea that America would be at risk of terror under Clinton.

“Wake up America FBI director warns an attack like never seen before here in America will happen. We can’t afford risk American lives with Hilary Clinton. They will infiltrate refugees guaranteed,” the person wrote.

Clinton was one of the 12 people targeted by the mailings. On Twitter, the account under the handle @hardrock2016 posted about several of the other mail bomb targets, including the liberal donor George Soros, who has long been a focus of right-wing conspiracy theories. @hardrock2016 also made multiple posts attacking gun control activists and Democratic Florida gubernatorial candidate Andrew Gillum as being “BACKED BY GEORGE SOROS.” One image retweeted by the account on Monday declared, “THE WORLD IS WAKING UP TO THE HORRORS OF GEORGE SOROS.” The person identified as Sayoc also posted images encouraging people to “VOTE REPUBLICAN” in the November midterm elections and expressing hope for a “RED WAVE.”

Postings that seem to have come from Sayoc don’t just express admiration for Trump’s politics. In an October 2016 Facebook post, Sayoc credits Trump’s business strategies with helping him open a sports bar.

“Thank you President Trump for all advice strategies, that worked to close on our soon to be … Knockers Sports Grill. We followed exactly the formate you laid out for us,” Sayoc wrote.
