Washington Post: On 24 August 1970, four antiwar activists planted a bomb next to Sterling Hall on the Madison campus of the University of Wisconsin. The explosion, which took place at 3:40am, killed physics postdoc Robert Fassnacht, severely damaged the physics department, but barely affected the bombers’ target, the Army Mathematics Research Center. By 1977 three of the suspected bombers had been arrested. The fourth, Leo Burt, remains on the run. As the Washington Post‘s Jerry Markon reports, the FBI has stepped up its hunt for Burt, 40 years after the bombing took place.
