For law enforcement officials who've spent several days investigating a wave of crude pipe bombs mailed to CNN and prominent figures across the country, removing the devices safely is just the beginning.
"Examinations are now underway at the FBI lab in Quantico," said Bill Sweeney, the Assistant Director in Charge of FBI New York.
That work is happening at TEDAC, the FBI's Terrorist Explosive Device Analytical Center in Virginia. It's the country's bomb library, a central location with an archive of more than 100,000 explosive devices from more than 50 nations.
"We are working quickly to process and analyze relevant information from the suspicious packages recovered over the last few days," Sweeney said at a briefing on the investigation Thursday afternoon.
Law enforcement sources tell the NY1 Investigative Team that all 10 devices bear similarities: A metal pipe with wires, tape, shrapnel, and a timer.
But were the devices capable of detonating?
"Any device could be considered potentially dangerous and treated as such until proven otherwise," Sweeney said.
Experts say one of the devices likely will be blown up in Quantico — much like in an FBI demonstration video seen above — to determine its potential power.
Inside a room at TEDAC, technicians will look to see if any tools were used to create the devices. When tools are used, they leave a distinct mark, allowing investigators to link devices and prove associations.
They'll also check every component, looking for serial numbers on wires and the types of pipe and tape used — all potential clues that may lead to where they were sold.
They'll also use standard forensic tools to identify the suspect, like looking for fingerprints, DNA, hairs, and fibers.
"The folks at the lab in Quantico are extremely thorough and every one will be examined in great detail," Sweeney said.
Investigators also will examine the packages, looking for postmarks that could point to where the packages were mailed.
Working in the investigators' favor is that there were many devices and nearly all of them are intact — a trove of evidence in a still-unfolding case.
