FBI offers reward for 1970 bomber. [View all]

More than 50 years after a Vietnam War-era bombing on the University of Wisconsin campus that killed a researcher, the FBI on Thursday released age-processed photographs of a suspect who has thus far evaded law enforcement and been referred to as Wisconsin's state ghost.
Leo Burt was placed on the FBI's most wanted list immediately after the 1970 bombing of Sterling Hall and remains the last fugitive sought by the FBI in connection with radical anti-Vietnam War activities.
The bombers parked a stolen van packed with fertilizer and fuel outside the universitys Army Math Research Center in Sterling Hall and lit the fuse in the early morning hours of Aug. 24, 1970. The bomb attack, which was the nations most powerful until the 1995 Oklahoma City bombing, killed 33-year-old graduate student Robert Fassnacht, who was doing research in the middle of the night. It also injured other people and caused millions of dollars in damage. The bombers fled to Canada.
Three of the four wanted men were captured in the 1970s after trying to live underground. They were convicted, served short prison terms and resumed their lives.

I interviewed one of the three that were caught for a history book I wrote. That person ended up as a law aide in Oregon. I doubt they will ever find Burt until he dies.
