MIAMI, Fla.—It was just one fingerprint that helped lead the FBI to the Florida man accused of mailing bombs to critics of President Trump and prominent Democrats, according to CBS News.
CBS says the investigation kicked into high gear after at least 13 packages containing what the FBI is calling improvised explosive devices, or IEDs were discovered across the county.

Those devices were sent to the FBI’s bomb lab in Virginia. It was at that lab investigators found a fingerprint from one two packages addressed to California U.S. Representative Maxine Waters, according to CBS News.
The FBI matched the fingerprint and DNA to Cesar Sayoc and let Florida law enforcement know what was going on, CBS News reported.
Investigators used video surveillance near a postal facility in South Florida to identify Sayoc. Then they pinged and tracked his cell phone with an electronic device to find his location.
