In the first six days of September 1978 , a series of bombings struck Speedway . Initially there were no injuries ; however , the last bombing led to the amputation of Vietnam veteran Carl DeLong 's right leg , and left DeLong and his wife with several other injuries that required significant hospitalization and rehabilitation . DeLong committed suicide in February 1983 . Investigators traced the Mark-Time timer and the Tovex 200 used in the bombings to Kimberlin , and he was placed under surveillance . The police believed that Kimberlin had conducted the Speedway bombings to divert attention from the murder investigation
