Cesar Sayoc, the man who is accused of sending 13 pipe bombs through the mail to a range of Democrats and critics of President Trump, left forensic and digital evidence behind that authorities used to track him down and arrest him. According to authorities, they were able to link the DNA found on two bomb packages to a sample that was previously collected by the state of Florida, as well as matching Sayoc’s fingerprints to one from a separate mailing that law enforcement officials said he had previously sent. Investigators also said they had scrutinized Sayoc’s social media accounts and found identical spelling mistakes on his online posts; such as “Hilary” Clinton, and Debbie Wasserman “Shultz”, which matched the mailings he has been charged with sending. Other social media posts by Sayoc trafficked in online conspiracy theories, anti-Semitism and white supremacy. Authorities say this evidence is what led them to the 56-year-old, who had a long criminal history and appeared to be living in his van, showering on the beach or at a local fitness center. Sayoc has been charged with five federal crimes as of Friday.
