A fingerprint and two DNA samples was all authorities needed to arrest Cesar Altieri Sayoc Jr. for his suspected role in mailing out more than a dozen explosive devices to prominent Democrats, FBI Director Christopher Wray said Friday.
Wray told reporters at the Justice Department’s headquarters that one of Sayoc's fingerprint was found on the package mailed to Rep. Maxine Waters, D-Calif., and that his DNA was found on two other packages. The DNA samples were connected to a sample collected from a prior arrest of Sayoc’s, said Wray.
Sayoc has been charged with five federal crimes, interstate transportation of an explosive, illegal mailing of explosives, threats against former presidents and certain other persons, threatening interstate communications and assaulting current and former federal officers.
It is unclear when Sayoc will be arraigned, but it is likely he will make an initial appearance in Florida before being extradited to New York, where the criminal complaint against him was filed on Friday.
A Justice Department spokesperson clarified Attorney General Jeff Sessions' remarks on how many years in prison he faces. Sessions had said up to 58 years, when in total, Sayoc could be behind bars for up to 48 years.
Wray declined to comment when asked if political rhetoric was a motivator for the sending of the explosives.
“We're focused on the work, not on the talk,” Wray said, adding, “We do believe that we've caught the right guy."
"I don't know," Sessions said when asked why the alleged bomber targeted Democrats. "Other than what you might expect. He appeared to be a partisan."

The criminal complaint against Sayoc filed in the Southern District of New York confirms that a “latent fingerprint” was detected on the package sent to Waters. DNA from Sayoc was also on the Waters package, the complaint reveals.
In addition, there was DNA collected from the package sent to former President Barack Obama.
“[T]here is a possible DNA association between a sample collected from a piece of the IED inside the Obama Package and a sample collected from Sayoc by the Florida Department of Law Enforcement, and to this point, the FBI Lab has not identified any other possible matches on the evidence from the Packages that it has examined,” the complaint said.
Thirteen IEDs were sent to various people around the country, Wray confirmed. The IEDS each had PVP pipe, a battery and other material.
"Though we're still analyzing the devices in our laboratory, these are not hoax devices," Wray said, adding that there could be other devices.
Because of this, Wray and other officials at the press briefing urged the public to be diligent.
Sayoc, 56, was taken into custody outside an AutoZone store in Plantation, Fla., earlier Friday morning.
Sayoc’s social media posts were mentioned in the criminal complaint, which noted that he had various posts on Twitter “with misspellings consistent with the Packages, including ‘Hilary’ rather than ‘Hillary,’ ‘Shultz’ rather than ‘Schultz." It also noted a "post dated October 24, 2018 — i.e., after the recovery of the Soros Package — that is critical of, among others, President Barack Obama and George Soros.”
The criminal complaint confirmed that the packages to the Obamas, the family of Hillary Clinton, actor Robert De Niro, Waters and former Vice President Joe Biden were routed through the U.S. Postal Service in Opa-locka, Fla., between Oct. 18 and Oct. 20.
