FBI director Chris Wray said a fingerprint on the package to Congresswoman Maxine Waters matched Sayoc’s. They were then able to locate him by using GPS on his mobile phone, which led to his arrest.
He said there could still be more devices out there, that they were not ‘hoax bombs’ and warned the public to be vigilant.
Officials said he has a long criminal history and used to live in Fort Lauderdale, as well as another past address in New Jersey.
After Sayoc was arrested, a van covered in pro-Trump bumper stickers was covered with a tarpaulin and taken to an FBI facility in Florida.
The stickers included slogans like “drain the swamp” and “CNN sucks”, as well as images of Hillary Clinton with a target on her face.
Sayoc’s tweets also accuse George Soros, one of the bomb targets, of paying off a victim of the Parkland mass shooting.
The suspect is believed to be Native American, and according to a picture posted on social media, he is a member of the Seminole Tribe of Florida.
His online footprint also suggests he is a former bodybuilder who worked in a strip club.
Public records have now revealed Sayoc has a series of criminal convictions dating back to the early 1990s, including for fraud, theft and drug charges — and most notably, a 2002 arrest for threatening to throw a bomb in a conversation with a Florida utility representative.
