South County car bomber

Two people – Shirley Marie Flynn and Robert Curtis Jackson – were killed in bombings on October 18, 1977, and November 3, 1977, respectively.^[2] A third victim, Ronald Sterghos, escaped injury in an earlier attack on October 7, 1977.^[2][3]

The bombings ceased after that and were never solved, despite an extensive effort by police.^[2] The bombings have been described as random,^[1] and some investigators believed that they were the work of a deranged individual.^[1] Some authorities have, however, noted similarities between the St. Louis County bombings and a car bombing on March 7, 1978, in Paducah, Kentucky, in which William Ohlhausen, who had been Shirley Flynn's boyfriend, was seriously injured.^[3]
