(WBBM NEWSRADIO) -- The search is still on for a bombing suspect more than 50 years after a deadly explosion at the University of Wisconsin campus.
The FBI has released age-progression images that show what suspect Leo Frederick Burt looked like in August 1970 and what he may look like today.
Burt – who may go by the alias Eugene Donald Fieldston – has been a fugitive sought by the FBI since he allegedly had a hand in the fatal bombing. A stolen van full of explosive material was parked next to a research center at the UW Madison campus, and the resulting explosion killed a 33-year-old researcher and injured several others.
Burt was charged with sabotage, destruction of government property and conspiracy.
The FBI is offering a reward of up to $150,000 for information leading them to the suspect.
