MADISON, Wis. — The FBI released age-progressed photographs of a suspect wanted in connection to a bombing on the UW-Madison campus in 1970.

The FBI Milwaukee Field Office released the photographs of Leo Frederick Burt Thursday. He allegedly participated in the bombing of Sterling Hall on Aug. 24, 1970. The explosion's blast and fire resulted in the death of a 33-year-old researcher. Four others were severely injured. The bombing resulted in an estimated $6 million in damage.

According to the FBI, several days before the blast, explosives had been placed in a stolen panel truck located three blocks from the building.

On Sept. 2, 1970, four men were charged in the bombing. According to the FBI, the bombing at Sterling Hall, which housed an army mathematics research center, was a protest to the war in Vietnam.

Three of the four men were later arrested and convicted. However, the fourth man, Leo Burt, remains wanted.

The FBI says a light-colored, late-model vehicle (Corvair) was last seen leaving the area and Burt was identified as being inside it.

At the time, the bombing at Sterling Hall was the largest act of domestic violence in the U.S.

As part of the 53rd anniversary of the bombing, the FBI released a new series of images created using age-progression technology, as well as an original photograph of Burt obtained by the FBI in 1970.

The FBI is offering a reward of up to $150,000 for information leading to his arrest.
