FBI Updates Photo of Man Wanted In WI Terror Bomb Attack From 1970

In the more than 50 years since a bomb ripped through a mathematics center at the University of Wisconsin, killing a graduate student and injuring several others in an attack protesting the Vietnam War, the FBI has received hundreds of tips about the whereabouts of one of the suspects, Leo Burt. Just weeks after the attack on Aug. 24, 1970, a waitress in Cleveland was convinced that she had seen him. Years later, another tipster thought he had spotted Burt at a homeless shelter in Denver. One man said he had seen the fugitive working at a resort in Costa Rica. Burt was never found. Now, in an attempt to develop new leads, the FBI released new images of what Burt might look like today, aged 75, the New York Times reports.

In one of the images, he wears the same wire-framed round glasses that he wore as a young man. He remains wanted for sabotage, destruction of government property and conspiracy, and “should be considered armed and dangerous,” the FBI said. Burt, a University of Wisconsin student in his 20s at the time of the attack, was among four men who the authorities say plotted to bomb the mathematics center, committing the largest act of domestic terrorism at the time. The four men are said to have detonated a stolen truck containing fertilizer and fuel oil near Sterling Hall, the building that housed the mathematics center, which was affiliated with the U.S. Army. The blast and fire killed Robert Fassnacht, a 33-year-old physics researcher, and injured five others. Investigators at the time said the explosion caused around $6 million in damage.
