US law enforcement agencies intercepted at least 14 packages allegedly containing small amounts of explosive material, addressed to prominent Democratic National Committee (DNC) officials, as well as key DNC supporters, between Oct. 22-26.

Some of the suspicious packages were recovered without incident, though others triggered evacuations and brief transport disruptions in New York City, Washington, DC, Los Angeles, Miami, Sacramento, and elsewhere. So far, all suspected explosives have been neutralized, and no injuries have been reported. Police have one suspect, Cesar Sayoc, in custody; it is unclear whether Sayoc acted alone. Additional devices will likely be found in the coming days.

All suspected "pipe bombs" were reportedly shipped via the United States Postal Service (USPS) or private courier. There is a distinct targeting pattern, the incidents are linked, and the effort was clearly planned well in advance. Sayoc reportedly used the same post office in Florida to send the devices.

NYPD bomb squad on the scene of a reported suspicious package.

Police arrested Sayoc, a 56-year-old man from Aventura, Fla., on Oct. 26. Sayoc has a criminal arrest record stretching back to 1991, that includes felony theft, drug battery, fraud, and battery. He was also previously arrested for threatening to bomb the Florida Power & Light Company in 2002. He is a registered Republican and owns a van covered in pro-Trump and other politically charged decals. He declared bankruptcy in 2012, and several indicators suggest that Sayoc was homeless or living in his vehicle.


Sayoc faces five federal charges:
  • Interstate transportation of explosives
  • Illegal mailing of explosives
  • Threat against former presidents and certain other persons
  • Threatening interstate communications
  • Assaulting current and former federal officers


Regardless of his intent, however, Sayoc was clearly an inexperienced bombmaker. The devices in question were extremely rudimentary. It is unclear which explosive compound was used or even if the devices were operational. Even if the devices were functional, package bombs are not particularly effective for targeted assassinations or mass-casualty attacks. Package bombs are certainly lethal and can easily trigger panic, but they are often more preferred for the standoff they afford the attacker than the power or precision they yield. It is also possible that Sayoc did not intend to inflict serious harm, but rather aimed to send a message.  The suspected pipe bombs were shipped in parcels riddled with warning signs – misspelled address labels, postage stamps on courier envelopes, excessive packaging tape, and no attempt to conceal the devices or their initiating systems inside the packaging – all textbook red flags.


Looking Ahead

Additional incidents involving package bombs are likely in the coming days. Clients can mitigate this threat by establishing and disseminating clear processes and procedures for screening and handling deliveries. Employees should undergo routine training on responding to bomb threats. Clients should also establish thorough evacuation plans with clearly marked exit routes. Finally, companies are advised to maintain relationships with local law enforcement and coordinate evacuation drills as often as possible.
