The man accused of sending explosives to at least 15 prominent critics of President Trump had been planning since at least July, according to a letter filed by prosecutors Tuesday night in federal court. Cesar Sayoc, 56, was arrested Friday after letter-bombs were sent to figures such as Barack Obama, Hillary Clinton, and Robert De Niro. The letter noted that when investigators searched Sayoc’s phone, they found photos of Michelle Obama’s driver’s license, Joe Biden’s home, and George Soros. “The evidence of the defendant’s terror campaign is still being collected but is already overwhelming,” prosecutors wrote. “The defendant conducted a domestic terrorist attack targeting at least 15 victims with improvised explosive devices... that he sent to locations throughout the country in padded mailing envelopes.”
Shipping labels were found in his laptop’s documents, the first of which was saved on July 26. Sayoc’s internet search history shows he was looking for the addresses of targets as far back as July 15, when he searched for Hillary Clinton’s home address. According to prosecutors, the FBI also reportedly found DNA evidence “linked to Sayoc” on 10 of the explosive devices he allegedly mailed. His fingerprints were also found on two of the suspicious envelopes the devices were mailed in, prosecutors said.
