Law enforcement officials say they have recovered a list of what could be more than a 100 potential bomb targets from the van of Cesar Sayoc, a Florida man who was arrested and charged Friday for allegedly mailing packages with pipe bombs to a variety of Democratic figures.

Officials who spoke with the Miami Herald said investigators discovered the “hit list” while examining Sayoc’s van where he lived and in which he is suspected of crafting the hazardous devices.

The van was decorated with images supporting President Trump, in addition to images with crosshairs covering former President Barack Obama and former Secretary of State Hillary Clinton. Investigators say the vehicle is of interest because it contains items such as credit card receipts and bomb-making materials that tie Sayoc to the mail-bomb spree.

More than a dozen individuals were sent pipe bombs in manila envelopes, including Obama, Clinton, former Vice President Joe Biden, and others, according to an FBI criminal complaint. Although none of the devices have detonated, FBI Director Christopher Wray warned Friday that other packages may be on their way.

Sayoc, who is from Aventura, Fla., was charged Friday with interstate transportation of an explosive, illegal mailing of explosives, and threatening former presidents, among other things. He appeared in court on Monday and will remain in Miami until he is transferred to New York for his case to be formally prosecuted.

He has been arrested multiple times over the years, dating back to 1991.
