The FBI has joined the Bureau of Alcohol, Tobacco, Firearms, and Explosives investigation into two pipe bombs found along Sacramento freeways in the past month.
Graham Barlowe with the Bureau of Alcohol Tobacco, Firearms, and Explosives says the latest device -found Monday near the Arden exit of the Cap City Freeway- has been sent to the bureau's laboratory in the Bay Area.
""They're very experienced in developing evidence from their forensics examination of the devices. So they'll be looking for any kinds of trace evidence that remains on the device and they will relay that information to us."
The California Highway Patrol says the pipe bomb is very similar to another device found near the Stockton Boulevard exit of U.S. 50 a month ago.
Barlowe says whoever planted the bombs made no effort to disguise them.
"These particular devices tended to look like something suspicious. They were not camouflaged as something that they weren't. And so, if anyone sees something that looks like what they think would be a pipe bomb, they should report that to law enforcement immediately."
The CHP says both were "very live" and could have gone off if they had been picked up.
