On May 23, 1966, Loren Bollinger, a 40-year-old rocket scientist at Ohio State University in Columbus, was ambushed and shot to death outside his downtown office. Five bullets were extracted from his corpse, including one which pierced the brain; ballistics tests linked the .25-caliber weapon with the murders of two gas station attendants, in or near Columbus, in the past eight months. Appealing for public help in their search for the gunman, police also connected the weapon with a case from September 1965, in which another service station attendant was robbed, then wounded and left for dead by his male assailant. In spite of a description offered by the sole surviving victim , homicide investigators are no closer to solution of the case at present than they were in 1966.
