Kent State shootings on May 4, 1970, in which four protesters were shot and killed by the
Ohio National Guard, they conceived of an attack on the Army Mathematics Research Center at the University of Wisconsin, which had been a frequent site of anti-War protests. Karl made a bomb out of dynamite, of fuel oil and of

The bomb was placed in a stolen van left next to Sterling Hall, a building that housed the Army Mathematics Research Center, as well as the university's physics department. They lit the fuse after checking the windows of Sterling Hall and seeing no activity, assuming that the building was empty. A bomb threat was phoned in to the Madison Police Department, giving five minutes notice of the planned detonation, though previous such calls turned out to be pranks. A police cruiser was dispatched to the site minutes before the explosion. The bomb detonated at 3:42 a.m. on August 24, 1970, killing
Robert Fassnacht, a physics post-doctoral researcher who was working late, injuring three others, and causing millions of dollars in damage to the building.
