The McNamara Brother's Suitcase

Origin
John J and James B. McNamara were the pair behind the bombing of the Los Angeles Times (LAT) building in Los Angeles, California. The initial explosion didn't kill anyone however the fire that came from it killed twenty one employees and injured one hundred more. On October 1st 1910 at 1am a suitcase bomb went off in the alley outside the LAT building. It was originally meant to go off at 4am when the building was empty but the clock timing mechanism was faulty. The bomb wasn't large enough to level the building however they were unaware of the presence of natural gas main lines under the building. The bomb collapsed the side of the building, the exploded gas main lit the building on fire. Unexploded bombs were later discovered at several prosperous members of society.
