After the two brothers engaged in a gun battle with police early Friday, authorities found many unexploded homemade bombs at the scene, along with more than 250 rounds of ammunition.
After the MIT shooting, the brothers allegedly used a gun to steal a Mercedes sport-utility vehicle, briefly kidnapping the driver and telling him they were responsible for the bombings, U.S. officials said.
At the climax of the 1980 movie "The Blues Brothers, " hundreds of gun-toting police officers, state troopers and other riotous authority figures scramble after John Belushi and Dan Aykroyd as they calmly ride a Chicago City Hall elevator while being soothed by a piped-in instrumental version.
