How Authorities Found Cesar Sayoc

One single fingerprint on a package mailed to Rep. Maxine Waters helped investigators find the man who allegedly sent at least 13 suspected pipe bombs to Democratic figures this past week, officials said yesterday.

The big break in the case for investigators came Thursday, when officials were able to trace five packages to the Opa-Locka processing and distribution center outside of Miami.

That discovery allowed authorities to narrow their search, which — combined with the fingerprint samples collected from the package sent to Waters and cell phone geolocation information — led to the arrest of suspect Cesar Sayoc, even as new devices were being found in New York and California.

“Once I knew that they had a print, I was pretty confident we’d be able to find the right person,” FBI director Chris Wray said at a press conference Friday.

Additionally, investigators also found a possible DNA connection between samples on two separate packages and material collected from the suspect, Cesar Sayoc, in a previous arrest in Florida, Wray added.

Sayoc, 56, was arrested in Plantation, Florida, earlier yesterday and was charged with five federal crimes — including interstate transportation of an explosive, illegal mailing of explosives and threats against former presidents, officials said.

He will be prosecuted in Manhattan, and faces up to 58 years behind bars AG Jeff Sessions explained Friday.
