When Lois was almost murdered, Bowman and his men searched the area for clues. Lois suspected of him doing it due to the loss of his promotion but it was revealed Lynteer did it.
Later on, Bowman murdered a rich woman and framed a petty thief Walker for doing it which was a success. Five years later, Walker is sentenced to be executed but Clark did his own investigation and figured out Walker is not guilty of the murder. Bowman was suspicious that Kent was getting close to the real killer. He planted a bomb in his car to kill him but Clark managed to survive because he is Superman which jeopardizes his secret identity. Bowman planted a bomb in Kent's apartment to make sure there are no evidence. Lois and Superman found out Bowman was the real murderer. Kurt tried to kill Lois by pushing her off a stairwell but she was saved by Superman. Bowman rushed to the helicopter and flew away. He launched rockets at Superman but the Man of Steel stopped Bowman who was later arrested and stopped Walker's execution. Bowman was convicted of murder and sentenced to be executed. He was escorted to the gas chamber and wondered how Clark survived the car bomb. In his final moments, he realized that Kent is Superman but the lever was pulled shortly after and Kurt couldn't tell anyone after.
